Definitely was a hack, I could not get your screenshots and there was only a way to write demonstrarion through the server. I've played with you for a long time, but last time you played much better than @Kenai hehe
Updated: If you did not violate anything, then why didn't you immediately apply application?
Your PlayerID and the ban reason show up when you try to join one of our servers. The PlayerID is a long line of digits, I'm going to assume this is yours 2310346614624095766.
The Admin that banned you will have to submit their proof here, if no proof is supplied then it'll default to an unban without proof.
