ATTN ADMINS: Vicky ?? Help.

Hello.

So I just got out of a game. I have a game saved. Vicky, from the clan "Lucky Stripes" decided to jump into the Wall in the Map Christmas and shoot and kill people throughout a couple of rounds. Not the crouch and be half in map half out as MOST of you see everyday but completely INSIDE THE WALL. Unable to kill. Who do I speak to? Who do I send the file to? This player needs to have a permanent ban in place. This was my first unpleasant Crossfire gaming experience and hopefully it's my last.
