Why is my brother banned?

Considering AmAz3 and Troy are the same person... Not sure, but I wish it was a legit ban.

I'll unban YOU when maintenance is completed.

No idea who banned him, but I think (not 100% sure) that the last time the server crashed like this it randomly banned some people, so MAYBE it's that.
