If this is not the case, how come the message still hasn't been reported to a moderator so it could be verified?
It was. But in the other thread (which messed up everything).
Op sent me the PM so I can confirm that's real at least.
Gleb verified himself after the PM in OP. Thus I'd say it's reasonable to assume they are still in control of their account.
I don't think he is. Whoever bought the account probably just asked him to send some proof to get out of the mess. Either way I don't really trust Gleb.
