Yes, yes they are. However the amount of aimbotters aren't as high as you think it's likely 1-2 out of 30 players has cheats on a lot try to play legit due to how fairfight works if they aimbot the game data will tell and fairfight bans them rather quick.
Some only even got ESP or as many uneducated like to call it wallhacks(which hasn't been used for years)
