Fake Twitter Followers: An Easy and Dangerous ... - The Next Web

Sitting cross-legged in the leather chair of my home office, it took me fifteen seconds to find someone who was willing to sell me 2,500 ?quality Twitter followers? to boost my account ? for the low price of about $25 bucks. The followers would arrive in three days and stick around for the whole year, more than doubling my current follower count of around 1250. I felt pretty comfortably smug about myself, especially considering I?d gotten this far by dumbly typing in ?How to buy Twitter followers? into my Chrome bar. I leaned in, determined to make the transaction, and tried to convince myself to click the button.

But, perhaps unsurprisingly, I couldn?t bring myself to do it. The taboo of actually buying my own followers, and the risks associated with real fans finding out, gave the experience a sort of grime that deterred me from going through with it.

That doesn?t mean it deters everyone: The practice of buying Twitter followers (or Facebook fans, Instagram followers, etc.) is as old as social media itself, hinged on the archaic notion that quantity trumps all in the social interaction sphere. Some of the most well-known politicians and celebrities in our social strata are accused of puffing up their own numbers with these followers ? often assessed as thoughtless and friendless robots keen on spamming Viagra ads ? to make themselves seem more influential and dominant on the platform of choice. But, on the other side of the coin, startups and rookie social media experts can just as easily be drawn in by a siren song of this so-called ?follower economy,? with its promise of instant credibility and cache in the wider community.

However, for all of the ethical red flags that seem to perk up in the face of buying followers, screaming ?scandal!? from just about every corner of the Internet, the follower economy is actually full of a lot of particulars that make the lines somewhat blurry. Throw in more legitimate marketing practices, such as paying for a promoted hashtag or tweet or building a ?core retweet? base of friends and family, and lots of gray areas begin to come into view.

Buying followers is morally dubious, possibly dangerous and can tear down even the most trusted social media figures, yet it?s poised to continue to grow in the immediate future. But hey, it can get you friends, right?

Caught red-handed

Turns out, buying followers is probably the worst kept secret in all of social media ? and it has a potential for a nasty and public backlash. Presidential hopeful Mitt Romney experienced one such scandal in late July, when his Twitter automagically garnered 116,000 followers in a single day; suspicious, no? At its core, the methods for paid follower installation are painfully obvious: the lump sum of purchased followers simply shows up in a person?s fan count all at once, with no staggering or reason. It just takes an astute eye and the handy use of a follower trending tool like Twitter Counter (disclosure: Twitter Counter is a product of TNW Labs)?to uncover when a follower purchase has taken place.

One such eye belongs to Tim Farley, a software developer and fellow at the James Randi Educational Foundation, where he studies and debunks hoaxes. Intrigued with the implications and accusations flying during the political cycle, Farley began looking at the activities of a Californian political group assembled for an election proposition called ?CA Right To Know.? The number of followers ? which jumped up as high as 95,000 sudden bursts ? struck Farley.

?You can see spikes in people?s follower counts, especially when it?s a celebrity in the news and things like that. But, a spike of 10,000 followers is just really really odd,? Farley says.

Full of skepticism, Farley ran the company?s twitter handle, @CARightToKnow, through Twitter Counter and found a distinct pattern within the handle?s follower base: The follower count would make a distinct jump within a 24-hour period, then begin to drop at a steady rate almost immediately after the boost. He then cross-referenced it with a second tool, StatusPeople?s Fake Follower check. From just a few minutes of searching and a healthy dose of common sense, Farley?s hunch proved spot on.

?It?s almost exactly a 10,000 follower jump right after September 17. Then right after October 2nd, it?s another 10,000 follower jump. Then after October 26th, it?s another 10,000 jump,? Farley explains. ?They were clearly buying followers in 10,000 person batches.?

CA Right To Know?s role as an ?abuser? ? a repeat customer of buying these fake Twitter followers, gave Farley a commonly felt feeling that the group was producing a falsely trumped-up image and crossing an ethical line.

?I think it?s shady because clearly those followers are just robotically created accounts ? they don?t generate any value for you,? Farley says. ?The only way is to boost that number up, and if you?re doing it this way, you?re lying.?

But it?s not just the big guys that are looking for a fast way to appear savvy on a social media platform: Smaller companies, businesses and even individuals looking to become go-to ?experts? in their field are also turning to the follower economy to inflate their numbers and lend an air of legitimacy to their presence. When Pennsylvania physician Dr. Robert Belluso decided to pursue his dream of developing a mobile game, he threw all of his resources into learning how to build everything from the ground up. By the time he finished his first game, Little Bird, he realized he lacked the knowledge and financial resources to build an organic social media following, so he turned to purchasing followers to jumpstart his presence on Twitter.

?Everyone?s looking for a quick fix, and they don?t want to wait ? it takes a long time to get legitimate followers on Twitter,? Dr. Belluso says, ?I didn?t buy 50,000 or anything, just an experiment of 500 followers to see how it would go.?

The result, Dr. Belluso felt, was really lackluster. Although initially he felt that the boost in followers would help him gain a stronger base faster, he ended up driving away followers. And, with an account broadcasting to purchased followers, he felt as though he was talking to a wall.

?None of those people went on to purchase my app,? Dr. Belluso says, ?And people just think ?Oh, if you get the numbers, you?re automatically socially relevant.? But that?s not true, that?s not the case.?

On top of it all, he felt that the followers he bought did exactly the opposite of what he intended, forcing him to rethink his strategy from step one.

?I found the best way now is to just be consistent and just have a conversation with people,? Dr. Belluso said. ?That?s the way to get fans. When I tweet, I can get up to 20 followers just based on that ? and that?s important to me because they want to talk about what I want to discuss and they listen to what I?m trying to promote.?

Not just unethical

Disappointment?is the worst thing that happened to Dr. Belluso, but buying followers runs a lot more risk than feeling like a fraud or a fool. Fake followers can incur phishing, hacking and even infecting?real fans with spammy links. Security solutions company Barracuda Networks?performed a study on fake follower accounts in August, and uncovered plenty of dangers hidden within fake followers.

?Hackers spend a lot of time preying on social networks, and they?ll try any method to do it,? explains Paul Judge, chief researcher at Barracuda Labs. ?And when we looked at Twitter, we saw that attackers have become very efficient at utilizing the viral features in Twitter to carry own attacks, which are found in those fake follower accounts.?

These risks, of course, are born out of the natural way the follower economy has grown ? and can be easily felt when visiting the ?online marketing? of?Fiverr.com?or one of the 78 different outlets that pop up when you search ?buy Twitter followers? on Google. People who deal in fake followers can certainly earn as much as $800 per day building programs to flood the network with dummy accounts, but that?s not the only revenue stream possible in the transaction. For one, Judge offers this piece of common sense:

?Did you pay for your followers with a credit card? If so, a hacker who makes fake followers now has your credit card number.?

But often it?s not just the dealers who are cause for alarm ? abusers are also, according to research found within the study, actors in fairly shady dealings. One of the biggest reasons abusers buy Twitter followers (aside from appearing popular) is to sell ads to others on Facebook. This is where the defrauded become the fraud, relying on bolstered numbers to dupe others into legitimacy. In a lot of ways, the biggest victims of purchasing followers are others on the platform who believe the lies or bear the brunt of the endless waves of spam.

Unsurprisingly, this is exactly the kind of behaviors security firms like Barracuda Labs want to prevent.

?The goal is ?How do we protect our customers?? Judge says. ?We want users to not interact with these fake follower accounts so they can stay secure and prevent a hacking incident.?

The new conventional wisdom

Another part of the fake follower equation ? and one often ignored ? is the role of the marketer. Many companies come to marketing companies to simply ?build as many followers as possible,? and that leads to a problematic situation for those who have made their careers on growing and building follower bases on social media networks. If you could get your job done for $50, and receive a payment that?s an order of magnitude higher, what?s stopping marketers from doing that same thing?

It turns out, a lot: out of dozens of marketers, not a single one advocated for buying Twitter followers or fans for any platform.

?It?s a bad practice, ? says Jason Weaver, CEO of social CRM company Shoutlet. ?It reminds me of the early days of email when you would just spam the heck out of people and just hope that they buy your product.?

Weaver is a firm believer of the exact opposite philosophy many Twitter follower abusers hold: It?s not about the size of a follower group, but the quality of the follower counts. Just a handful of ?active followers? ? that is, people who are likely to retweet and engage with tweets ? are infinitely more valuable than hundreds of robotic place-fillers that are little more than a number. For example, Weaver worked with a healthcare client that specifically targeted anesthesiologists, which is a remarkably small subset of everyone in the healthcare profession.

?If this company found twelve anesthesiologists online versus hundreds of thousands of doctors and nurses, the former is a more quality connection than the latter,? Weaver explains. ?It really depends on getting in front of the right audience and putting effective content in front of them.?

But that doesn?t stop Weaver from encountering brands who still harbor ?old logic? ? that the follower count is more important than anything else that he or his company can offer. Instead of?acquiescing, Weaver says he?s happy to push back on a company to get to the core of what they?re after.

?Companies who are inexperienced with social media are normally just into these numbers,? Weaver explains. ?When you crack a smart strategy with that company, they?ll usually say, ?Yeah, we thought step A was fans and followers, but what we really want is to sell another 10,000 units next year.? We can work backwards from that and find the best way to do it.?

And Weaver?s methods are no longer in the minority. In fact, as Twitter has moved from a fringe platform only occupied by tech-forward early adopters to a more mainstream environment, so has the conventional wisdom on how to build a following. Resource, a digital marketing agency that has worked with big-name brands such as Wendy?s and Victoria?s Secret, conducted an experiment with a food product company that was having trouble boosting their follow count. The company then employed a ?1 to 1? strategy ? a popular method that eliminates common practices like follower reciprocation (follow me and get a follow back!) and forces a brand to speak more like a person than a company promoting its wares.

?Just having that number doesn?t have the same cache that it used to,? says Resource Executive Director of Social Laura Schaeffer. ?People are more interested in engagement, what people are talking about and how that?s affecting your brand.?

The response was astounding, and the company was able to break the 10,000 follower mark without giveaways or paid media. And Schaeffer says that it all happened because of the connection.

?You have to show your brand personality, whether it?s intellectual, humor or cultural significance,? Shaeffer explains. ?Finding out what that niche is and figuring out how that can correlate to your product in some way, you can have double-digit growth in fan count or followers just by presenting relevant information.?

Resource also practices other methods for gaining followers organically, particularly ?active listening? ? which means that a brand will follow all mentions of their name or their competitors? names to reach consumers who are talking about the brand but not following ? and ?surprise and delight? ? reaching out to fans with gifts and giveaways that incentivize brand evangelizing and loyalty.

?There are ways that you can engage in cultural conversations in a way that puts you in a new light. It?s an awareness tool, it?s a tool for brand positioning, it?s a great place to launch a new product because you can get yourself on the radar with people who wouldn?t ever think to like you on Facebook or otherwise check you out,? Schaeffer says.

Marketers are doing their best to distance themselves from the follower count, branding it a ?vanity metric? and touting that an engaged base is better than a broad one. But that still leaves the question?

Is there a gray area?

Whether unethical, illogical, ineffective or dangerous, voices from all areas of social media are quick to label purchasing followers as a poor practice. Meanwhile, other concepts such as promoting hashtags and inserting ?sponsored stories? into a feed remain fully supported by companies, marketers and independent businesspeople alike.

Is the line so clearly drawn in the sand? As the nature and purpose of social media continues to change, the methods behind marketing and branding will change, too. Purchasing Twitter followers may become a thing of the past ? Barracuda Networks believes there?s a possibility that security measures could drastically decrease the practice over time. But that doesn?t mean that other methods won?t take on a shadier or more sinister approach to connecting with others in the future. At this point, though, the message is pretty clear. Buying followers is the easy route, but it?s like cheating during your favorite board game: you?re likely to be labeled a fraud and a cheat than win like you wanted to.

Plus, I checked my fake follower count and I?m at 1% ? why go messing around with those numbers?

Pakistan extends refugee status for Afghans

ISLAMABAD (AP) ? Pakistan has extended refugee status for over a million Afghans in the country by an additional six months, the government announced ? a move likely to ease fears of Afghans living in Pakistan that they would soon have to return home.

Pakistan has been hosting hundreds of thousands of Afghan refugees dating back to the Soviet invasion of Afghanistan three decades ago. But many Pakistanis have become increasingly frustrated with the length of time the Afghans have stayed and would like them to leave.

The Pakistani government said in a statement released late Wednesday that refugee status had been set to expire on Dec. 30 and that they would extend it for another six months. The statement said there are 1.6 million registered and 1 million unregistered Afghans in Pakistan.

The extension would not affect unregistered Afghans, who are considered illegal residents.

The Afghan population in Pakistan is a legacy of Afghanistan's repeated conflicts, starting with the Soviet Union's invasion in 1979.

Many refugees can't fathom returning to Afghanistan any time soon, saying their homeland is still too violent and desperately poor.

Ehsanullah Elaj, an Afghan refugee who is a dentist in the city of Rawalpindi next to Islamabad, questioned what would happen to the refugees after the six-month extension expires.

"It would be very difficult for us to return to Afghanistan," Elaj said. "The majority of people want to stay here."

The Islamabad government has said it will not forcibly evict Afghans, many of whom have children born and raised in Pakistan. However, revoking their refugee status would encourage people to return.

Refugee status allows Afghans to get a government ID card that they use for everyday activities like banking or registering for school.

In a statement, the U.N. High Commissioner for Refugees welcomed the extension but pointed out the uncertainty for Afghan refugees.

"While the six month extension is important, Afghan refugees will be left wondering what the future has in store in July 2013 and beyond. UNHCR will therefore continue to encourage the government to maintain asylum space in the challenging transitional period ahead," said Neill Wright, the U.N. agency's Pakistan representative.

The U.N. agency has said that 83,000 Afghans have gone back this year, a 40 percent increase in those returning to their homeland compared to 2011. The U.N. has been spearheading a program this year designed to help Afghan refugees return to their homeland.

How the Top 2 Candidates for Defense Secretary Differ

Chuck Hagel is, by his own admission, haunted by Vietnam. When asked to explain his early opposition to George W. Bush?s 2003 Iraq invasion in an interview in 2011, the former Nebraska senator harked back to his experience as an Army private fighting the Tet offensive in 1968. That maverick stance cost Hagel his reputation as a leading Republican, and it may be one reason why President Obama is now considering him as his next Defense secretary, with Leon Panetta set to retire. ?We sent home almost 16,000 body bags that year," Hagel told me. "And I always thought to myself, ?If I get through this, if I have the opportunity to influence anyone, I owe it to those guys to never let this happen again to the country.? ?

When Obama mounted a Bush-like ?surge? in Afghanistan in 2009, Hagel wasn?t happy either. ?I?m not sure we know what the hell we are doing in Afghanistan,? Hagel told me in 2010. ?It?s not sustainable at all. I think we?re marking time as we slaughter more young people.? Hagel had also opposed the surge in Iraq. In a dramatic moment on the Senate Foreign Relations Committee in 2007, Hagel implored his fellow Republicans to stop avoiding the truth about what he called the futile ?grinder? of Iraq, and asked them not to send in more troops. ?Don't hide anymore; none of us!? Hagel declared, raising his voice. Although several Republicans expressed misgivings, in the end?only Hagel voted in favor of the nonbinding resolution.

All of which raises a question: Is Chuck Hagel a pacifist? Hagel, a warrior who earned two Purple Hearts in Vietnam, would say certainly not. And he can lay claim to a certain amount of prescience; like Obama himself, who first came to national renown in 2002 by speaking against the planned Iraq invasion as a ?dumb war,? Hagel saw earlier than most in Washington the pitfalls of launching a new war (Iraq) in the middle of an ongoing one (Afghanistan). "Many of those who want to rush this country into war and think it would be so quick and easy don't know anything about war," he told me in the summer of 2002. "They come at it from an intellectual perspective versus having sat in jungles or foxholes and watched their friends get their heads blown off. I try to speak for those ghosts of the past a little bit."

Michele Flournoy, the former under secretary of Defense who is also a leading candidate to replace Panetta, is also somewhat haunted by the ghosts of Vietnam, by her own account, but in a very different way. Though far too young (she turned 52 on Friday) to have served there with the 66-year-old Hagel, Flournoy warned in a speech this week that military planners might still be too ?risk-averse? because of the Vietnam experience. She said the military was endangered by a new "Vietnam syndrome" in which planners might seek to avoid the lessons of counterinsurgency and guerrilla warfare simply because the last decade of this kind of conflict has been so costly in Iraq and Afghanistan.

At a time when Hagel was worried about the cost of the Afghan surge in body bags, Flournoy?was promoting the idea as a leading supporter of counterinsurgency strategy in 2009. During this period, a fierce debate occurred inside the Obama administration over whether to pare down the U.S. presence in Afghanistan and Pakistan to mere ?counterterror operations??the position taken by Vice President Joe Biden, a longtime Hagel ally?or whether to mount a larger counterinsurgency or ?hearts-and-minds,? nation-building-type war. After leaving the Pentagon, Flournoy?took over the Center for a New American Security, a think tank?known for its work in counterinsurgency policy.

Yet Flournoy is no neocon hawk, says her former Pentagon aide, Janine Davidson. ?She knows what battles to choose,? says Davidson, who worked as deputy assistant secretary for plans under Flournoy. ?She?s very pragmatic about the application of military in an engagement and prevention role.... [I] think she has a very grounded sense of what America?s role in the world should be should be and how the military should support that role.?

Hagel?s blunt views on Iraq and Afghanistan are a reminder that, if Obama is hoping to look bipartisan in naming a Republican to a top post, he?s not limiting himself to those in good standing with the GOP. Hagel, who was once seen as a potential Republican presidential nominee, became persona non grata inside the party after his opposition to Iraq and never regained his standing. Nor has he ever let up in his criticism of what he called ?mad, wild dash into Iraq,? which he blamed on ?the lack of any clear strategic critical thinking? about the causes of 9/11. ?I think when history is written of this 10-year period, it will record the folly of great-power overreach,? he said in 2011.

In the end, if Hagel is chosen, his views may be more in tune with the American public?s?and Obama?s. The American public is clearly war-weary. According to a new Pew poll, only about a quarter of Americans (27 percent) say the U.S. has a responsibility to do something about the fighting in Syria, while more than twice as many (63 percent) say it does not.

Yet Hagel?s blunt criticism of the Afghan surge, which has already been wound down (some 68,000 pre-surge U.S. troops remain in Afghanistan), would put him directly at odds with the president he would serve. In a 2010 interview, he also criticized the president?s decision to send in additional armor with the troops. ?It?s a huge mistake to get bogged down with over 100,000 American troops. And this latest decision to bring in armor, that?s astounding to me at a time when we?re trying to work our way out. When you sink in a battalion of armor, sophisticated tanks, you?re going in deeper. You?re not getting out. The optics of that go back to Vietnam. When people see tanks in their country, they think occupation. That?s not something that?s winnable.?

Micro sensors help underwater robots swim like fish

Dec. 12, 2012 ? NTU scientists have invented a 'sense-ational' device, similar to a string of 'feelers' found on the bodies of the Blind Cave Fish, which enables the fish to sense their surrounding and so navigate easily.

Using a combination of water pressure and computer vision technology, the sensory device is able to give users a 3-D image of nearby objects and map its surroundings. The possible applications of this fish-inspired sensor are enormous. The sensor can potentially replace the expensive 'eyes and ears' on Autonomous Underwater Vehicles (AUVs), submarines and boats that currently rely on cameras and sonars to gather information about the environment around them.

The revolutionary, low-powered sensor is unlike cameras which cannot see in dark or murky waters; or sonars whose sound waves pose harm to some marine animals.

These extremely small sensors (each sensor is 1.8mm x 1.8mm) are now being used in AUVs developed by researchers from Singapore-MIT Alliance for Research and Technology (SMART), a research centre funded by the National Research Foundation. The centre is developing a new generation of underwater 'stingray-like' robots and autonomous surface vessels.

The new sensors, made using Microelectromechanical Systems (MEMS) technology, will make such robots smarter and prolong their operational time as battery power is conserved.

Associate Professor Miao Jianminfrom the School of Mechanical and Aerospace Engineering, and his team of four have spent the last five years in collaboration with SMART to develop micro-sensors that mimic the row of 'feelers' on both sides of the Blind cave fish's body.

Associate Prof Miao said the line of sensors present on the fish's body is the reason why it can sense objects around it and still travel at high speeds without colliding with any underwater obstacles.

"To mimic nature, our team created microscopic sensory pillars wrapped in hydrogel -- a material which is similar to the natural neuromasts of the blind cave fish -- into an array of two rows of five sensors," Prof Miao said.

"This array of micro-sensors will then allow AUVs to locate, identify, and classify obstacles and objects in water through water pressure and also to optimise its movement in water by sensing the water flow."

The new sensor array which costs below S$100 to make, is also more affordable than sonars, which can detect faraway objects but not nearby objects and cost thousands of dollars.

Partnering Prof Miao to develop the sensors and to adopt it for use on AUVs is Professor Michael Triantafyllou from SMART. Prof Triantafyllou, from SMART's Centre for Environmental Sensing and Modeling (CENSAM), is one of the world's foremost experts on creating underwater robots modelled after aquatic animals like fish.

Current problems with AUVs include poor navigation in murky or cloudy waters such as those off the coast of Singapore, as underwater cameras can only see a short distance, Prof Triantafyllou said.

"Other methods like underwater lights and cameras, acoustic navigation, and sonars also work, but they are very expensive and require very high levels of power that drain the batteries. The new sensors are much cheaper and only require small amounts of power. Also, sensors like sonar are loud and invasive and they may harm aquatic animals that also use sound waves to navigate," the Massachusetts Institute of Technology professor added.

The aim of the AUVs is for environmental sensing, to detect environmental pollution, contaminants and to monitor the overall water quality in Singapore's waters. The AUVs will have chemical sensors installed to detect the chemical condition of water (dissolved oxygen, nutrients, metals, oils, and pesticides), and biological sensors to monitor water conditions such as harmful bacteria and pathogens.

Other potential application of these MEMS sensors, which specialises in near-field detection include defence applications. These can detect nearby submarines without the use of sonar thatgives away one's location.

This collaborative research resulted in two breakthrough papers being accepted for presentation at a MEMS conference next January in Taiwan, organised by the Institute of Electrical and Electronics Engineers (IEEE).

One paper is for the development of the piezoelectric sensor which does not require any energy as it generates an electric voltage when water flows past the 'feelers'. The second paper focuses on a low-powered biomimetic sensor which can detect underwater objects even when there is little water flowing past it.

To further improve the sensor, Prof Miao's team is now looking to develop a hybrid sensor which will combine both the zero-energy piezoelectric sensor's high accuracy with the low-powered static sensor's ability to detect objects in still water.
