Massucci's Take: Fake Twitter users are good for Twitter, bad for you
Think of Twitter as another in-box. By following someone on Twitter, you are electing to receive mini Twitter e-mails, known as Tweets, from those new pals. But there is a growing problem: Those new pals may not be who they say they are.
Fake users are not a big problem for Twitter - they help the company's growth. But they are a problem for users. I exchange Tweets with about 500 people on Twitter. If one of them sends spam or attempts to sell something, I'll likely un-follow them. No problem. Tweeting with fake users, on the other hand, isn't always so obvious.
