Facebook, Twitter and YouTube, the social sites used by the most people and therefore possessing the greatest reach, each have their hazards. Twitter allows users to easily @mention a brand, drawing attention from company observers. But Twitter posts also spread very quickly, and users can easily retweet a comment or post without checking its validity, allowing a crisis to explode across the service.
People are buying followers. Yes, you read that right. Sounds ridiculous, but a lot of people do it. Mostly public figures, but even us normal people do it too. In fact, at least 11,283 Twitter users have purchased more than 72,000 fake followers.
