Nah, this is meta because I'm searching for a specific member of this forum technically; rather than trying to find offsite resource.
All the drama and everything occurred here on this site; not off-site or some 3rd party site.
Tradefortress doesn't seem to be the underage user. As far as I know, this exchange wasn't hacked, but instead it shut down and refunded everyone.
Well it seems like it got moved
Also, if you're looking for a specific user, then the thread probably belongs to Reputation if I had to guess. Meta is about the forum itself as a software/platform etc, and not about the users of the forum. The reason why your thread probably got moved to exchanges is because your topic is pretty vague.
Also going to need more hints than what you're currently offering. My brain is too doo-doo.
