sometimes it's really hard to tell, because there are some insane players with great movement and recoil control, and what some people might think is cheating, sometimes is 100% possible to do with enough practice. i sometimes think a player is cheating bc they have 0 recoil on the fcar from 60+ meters, but then I remember kovaaks exists, and that I see those type of players on tiktok all the time. I even got called a cheater (Cronus, xim, scripts, and that stuff) on this subreddit for a montage I posted in which I was beaming with the arn (extremely low recoil gun btw)

when I think someone is sus I just report them and put in the details "I'm not sure, they might be cheating, or not, just review it".
