I play at least 5 games on Comp a day. As Long as you basically play like you "Don't" have cheats you will be fine and I always try to stay close to mine and other team top kills. I use aimbot but only when another person seems to be cheating and also I always watch my spectator list, That is a big key as well.
just a friendly tip i use like super low fov, and always check forums before use, use wh but just dont do anything rational until you hear something. And also i find chams quite handy, so they don't blend in with the environment.
