Following on Twitter

I just realized, in order to follow a "real" celebrity, the top of their profile contains a checkmark and says 'verified account' next to it. That's how you can decipher the celebrities from the fakes. Besides celebrities, you can search just about anything or anyone or any company on twitter, and most non-celebrities are not going to have "fake" accounts anyway. However, some companies may have "fake account" like dunkin donuts, for example.
