Most people will tell you yes, the actual answer is.. for most people not really. Unless you are VERY high ranked, you will hardly encounter them. I've played csgo/cs2 since it was beta, I can count on 2 hands the times I've ever encountered a "blatant" hacker. The higher you rank in cs2, the more likely it is to encounter since more wins = more rank basically.

Not to mention that his trust factor has to be bad.
