Many people use TrueTwit or other follower validation services to try to ensure that all their Twitter followers are real. In Twitter’s IPO filing, the company estimated that up to 5 percent of Twitter users were fake. You may wonder what fake followers are, and why they exist. Generally, fake followers exist only to spam you. Additionally, fake followers might assist bad guys in stealing your identity.
So the concern is real. But why punish real people because some unscrupulous people might follow you, especially when there are alternatives?
