He needs to appeal. This is a newer ban wave that has been going on since the beginning of June. Over 150 people have been nailed with it so far., All the same violation number. #81668
Its actually an Evenbalance (Punkbuster) violation, not PBBANS. You have to remember even no recoil or no smoke is a cheat. Cheats are not limited to just aimbots and wallhacks
Like I said this latest ban wave violation has been going on since the beginning of June. If you have played since then and are not banned, you are safe. lol
