CSGO hacker problems

Have some years that CS:GO have many hackers
Sometimes it's hard to see, like lucky
I play with one, he was my enemy and he shoot before someone appear, type feel
but was wall hacker, pro players do it but play many years and take the time, fast, or he see the enemy and shoot at the time that the enemy move, you know, i can mistake but you that play know that
hack of headshot - with USP - one shoot one headshot :(
but i love CS:GO and miss it
one day i will play again <3
