An anonymous reader writes: In a new study, Barracuda Labs analyzed a random sampling of more than 70,000 fake Twitter accounts that are being used to sell fake Twitter followers. They also analyzed some of the people that are using such fake followers including the recent example of U.S. presidential candidate Mitt Romney’s Twitter account. Between Facebook’s 10-Q filing stating that 83 million of its accounts are fake, to Mitt Romney’s Twitter account recently falling under scrutiny for suspicious followings, fake social network profiles are a hot topic at the moment. And these fake profiles are at the center of a very vibrant and growing underground economy. This underground economy consists of dealers who create and sell the use of thousands of fake social accounts, and abusers who buy follows or likes from these fake accounts to boost their perceived popularity, sell advertising based on their now large social audience or conduct other malicious activity.
