I nominate this guy:
(Below a short conversation on a server, and yes this actually happened)
Player 1 + 2 Having a conversation about the clan,where its going,their mascot yada yada.
Me

lease refrain from discussing clan matters on our servers.It is a private matter between you and your clan mates.Players on server do not wish to read your clan chatter.
Player1:Ok sorry, spartan usually you are full of jokes,why are you so angry?
Me:Emotion has nothing to do with my job.I enforce the rules
Player2.This is so UNFAIR!
Me:Whats unfair?
Player2:You warn us but when other clans do it like clan ***** you let them do it...
Me:I saw you doing it and I did not see them doing it,had I seen them I would have warned them as well.
Player2:THIS IS UNFAIR!YOU ALLOW THEM TO DO IT!
Me:I say again,I did not see them do it,how can I warn for something I did not SEE.
Player 1:Spartan chill, praat jy afrikaans?
Me:Tell your clan mate to chill.
Player 1:Ok I will
Player 1:***** die admin is a doos
Player 2:Ja hy is
Player 1:Ok spartan I told him
At this point I let on that I do understand afrikaans and banned both of them.
I nominate these two.
