Just ignore/mute the trolls. Personally, I wouldn't even bother with TKing him, as that could net you a ban if he was in bitchy enough mood to take a screenshots. Anyway, as I said, I don't care if someone insults me or our clan and there is no point in trying to defend ourselves, as they will just continue to troll even more. Our results speak for themselves, and I couldn't care less if some peasant/my old friend (pun intended) is calling me noob ^^
