Having had just arrived, I'm not in a position to do much more than observe. However, I seem to have come it at the height of the tidal wave.
Deliberate misrepresentation of oneself on the internet is as old as... well, the internet. Reasons vary: to say things behind the veil of anonymity, to say things for which their "real self" might not be taken seriously, to get attention, to manipulate others, &ct. It seems in this case, this guy is a case of the last. Making outlandishly false claims (being an an institution, having been raped, &ct) is just manipulative, controlling and horrible.
Some argue "oh, it's the internet, we can always just play pretend", and there's a point to that. But that point isn't valid here. Just garnering attention and sympathy for horrible things some here have experienced, first or send-hand, isn't playing; it's trolling.
I honestly mean that.
I doubt you honestly anything.
