There are definitely people here who have been exposed as fakes and banned for it. I can think of two cases in particular, and each of their stories were particularly ghastly high-octane triggerfests that severely alarmed many people reading them - including me.
Well, their stories are still up here as emotional boobytraps. I don't know why the mods don't at least put a new signifier under the screen name - BANNED or FAKE or LIAR - so people will know not to waste their trust and sympathy.
