how many cheaters have you encountered?

Sometimes I can't tell if someone's cheating or not simply because they outplayed me and have really good aim but most cod players are just tryhards and play 7 hours a day but
if someones using aimbot u will immediately die in a few seconds and they usually have new account since they have been banned before. I have personally encountered only 2 cheaters that I am sure was using hacks.
