This guys gone through the effort of taking screens, uploading them, making a thread. If it benefits his life by giving us a few days ban, then why not.
Personally i don't see much wrong with having a bit of fun now and again, I don't recall TKing any randomers either? We were just having some fun between ourselves.
I guess if the crime is not being Mr 24/7 100% serious gamer, then all 3 of us are probably guilty. Regardless, I had fun yesterday and if by having that fun I get banned, so be it...
Best Wishes
