When blogger Louis Gray realized he was getting slammed with Twitter spam, he didn't take it sitting down. He started snapping screenshots, analyzing logs and eventually put together a package large enough to bring to Twitter's attention. His complaint? Automated refollows, a technique where spammers join a popular Twitter's follower list, then unfollow and refollow at particular times every day.
What's the point of refollowing? It's all about eyeballs. Everytime you follow someone, your Twitter account shoots to the top of their follower list. If they've got a LOT of followers, that means you can put a lot of eyeballs on your avatar, and you're bound to gain some followers simply by being noticed. Do that every day for a high-volume Twitter account, and you can put together a pretty big followers list pretty quickly.
That's what @Politicalupdate and @twtr.us were doing - at least, until Gray blogged about the irritance of refollows. After his sleuthing, Twitter suspended those accounts, and bloggers and Twitterers alike sang Gray's praises.
Twitter spam of all types has become more and more of a problem. The microblogging platform's stubborn refusal to install any kind of automation-busting tools (like a CAPTCHA) and the openness of their API means that if people can find a hole, they've got free reign to exploit it until someone brings it to Twitter's attention.
The good news? Twitter hears your woes. If you can put together evidence in the way that Gray did, and put it in front of Twitter, they'll take action - which, although not as good as pre-emptive spam prevention, is at least a sign that they are aware of the problems and that they care to help solve them.
What about you, Tweeple? Anyone out there had follow/refollow spam? Anyone out there a secret refollower spammer?
