They seem to have a habit of deleting accounts for no reason. After several emails asking for an explanation, they falsely accuse you of cheating and refuse to reactivate your account. They don't even seem to read your emails, they just send copypasta emails, so trying to explain that you weren't cheating is a waste of time. These guys can't tell the difference between bots and actual people, so they could delete anybody at any time. Don't waste your time on these guys.
