Which server is this?
All ok dude, but he was banned from the server because was cheating more hard :DLooks to me like he's just a good player. Use this opportunity and learn from him: spacial awareness (based on visual and auditory information), good crosshair placement at all times, recoil control, accuracy, ... is what makes a good player.
Go watch videos of actual cheaters who use aimbot & wallhack so in the future you will be able to better discern a skilled player from a cheater.
