"Because all in all, who would do this much work just to hack a server"
Maybe not a hacker, but a troll just might.
Ok Louie, here's the deal. Yes, you tried to log in with a BE globally banned account, then less that a minute later, (which shows you to be an adept key changer with multiple accounts), you tried to log in with an account that definitely was previously banned a while back for stealing by one of our admins. There is no question of this previous ban and zero chance of this not being true. It is impossible that our server software could pick up your unique 32 digit alpha-numeric GUID locally without you ever having previously logged on. You or your "brother" were indeed here before, perhaps you just don't remember. And indeed that account was banned here, so that is not the question.
The question is though : Were you or your <cough> "brother" banned fairly? It would have been a much better approach to appeal that point, rather than trying to use the obviously false argument of denying ever having been here. Now your integrity is in question.
So, with that out of the way, you have to make your case to the Admin staff to be un-banned. You are getting another chance to do that now. The ball is in your court. Can you do it?
