Was playing with him today, not so sure about his playing or rulebreaking because from my experience all he does is talk.
For a good 20 or 30 minutes the server was just an abusive chat between him and Machiavelli (who I see cluck has now posted here about, surprise surprise). They were clogging up the screen with their back and forth arguments and calling for each other to be banned. Can't remember what admin was present at the time but felt sorry for the headache they must've been getting off these two players.
So can't attest to his camping or any other such things, but in my experience he doesn't race, he just argues. As well as taking up valuable team space the chat and text just gets chocked full of his abuse. Not good at all.
