are hackers still common?

What kind of games are you playing? I see them pretty much everywhere. Tho it does depend on the rank you have in those games. Say if you play CSGO in silver 1 with low as fuck trust Factor. You'll only be playing againts spinbotters. But R6S in say GOLD is very hard to find a hacker.

it depends of the game popularitty way to exploid it and policyes of the game i think

Every GTA lobby i enter has one or two normally

Yup, Everywhere. It's Hard To Find An Actual Game Without Hackers D:

Im still here so i guess so.... Otherwise, i dont know

yes, alot of cheaters now days.. sadly
