Im almost always hacking when i enter a game, Iv even been caught useing aimbot because it tends to aim to the next closest target to me so after i kill someone i flip in entirely different direction and blast a wall. Then they ask me why i keep doing that and so far saying "having a crap mouse and having it at 100% mouse sensitivity" works best.
Oh! and a small tip for you speed hackers who just speed hack for fast kills, its best that you do it ina game that has atleast 50 kills left because that only takes a few seconds to make if your good. and they cant kick you and you just added 300-400 exp to your total
