I have read multiple threads on here already by people suspecting him of cheating and moderators not taking it seriously, but it might still be worth a try...

AimbuttUltra is 1000% a cheater. He takes 0 damage from rockets, slams of other anti-vehicle gadgets when he is in a tank and he knows exactly where you are from the moment you spawn. he doesnt die a single time when he is in the game. It is just so obvious that he is cheating. Even when addressing it in game the admins seem to defend him by saying he's just a good player. he is not. he is cheating.
