Corve made this thread for all of us, as this was the same situation.
Insults? Banning people without the correct procedures,
as you are saying yourself "you don't know server rules? BS!"- while you obviously don't know them yourself.
cuts from the rules, sunshine:
"Remember that this is the internet. Don't be insulted if someone calls you an idiot."
Also, I don't think I would have to mention again: NO WARNING, NO KICK, NO REASON FOR BAN GIVEN.
its not your first rodeo as an admin so this kind of "mistakes" are unacceptable.
rules are there for everybody on the server, yourself included.
If you believe you cannot deal with this situation, call another admin here to review the case.
EDIT: I called you fucking retard, once. and I wasn't calling for attention, I merely expressed my opinion that what you're doing is an act of lunacy, respectfully
