How to stop hacker?

You've got no choice but to report them, you can try to make report bots to be more efficient

Report , thats the only thing you can do for them. Game developers will take care of them

Stop playing that game can stop Hacker xD Learn something or Doing something without playing game

You can't. Only thing you can do is to get prime. But this doesnt helpt that much in the end

clean ur pc twice using disk clean and fragmentation

Report and stop playing for a while until them get cool down or bored and the mod patched the hack first

there is really nothing that you can do except report him and he will get banned for 100%
or he just smurfs and you can report him for grifing

I feel like reporting the bots are your best option.

If you wanna MM with less bots there are other sites hosting competetive csgo ( not sure if they still exist, haven't played for a while but I'm pretty sure they do. )

haha i have stopped playing that game a long time, time to play PUGB (but i realise PUBG also have hackers too)
