Also, use Arkan, and if you understand how AK "kickback or whatever it's called" works you will catch cheaters more often and easy. Arkan sends violation if you actually do trigger something but what do you actually trigger? Idk for other guns but for AK check if you try to do the pattern perfectly as possible. Because cheaters think recoil pattern is important they shoot straight at the victim and hit max 10-15 bullets MAX and their spray is not moving but because half of the ak bullets fire after the animation or whatever it is they do not go where you aim exactly... : D
So pro players that do practice know this and do not try to shoot straight but instead from shoulder to shoulder and etc and hit the bullets. The pro player can end up with a low score for the pattern but more hits like 15-20.
So if you see someone triggering arkan like crazy he just scripting or just thinks spray pattern is important only and live in UKN trying to beat the pattern UI :D
