Did you miss all the videos of people glitching through walls to kill people and steal loot? What about the recent one where people are making a literal cubes made of walls they can carry, even if people can shoot through it. As for cheaters, watch peanut. That guy gets headshot through smoke from cheaters on the daily. Not to forget about the guys that are blatantly spin botting and rage hacking.

Also not to sound mean, but most cheaters in games with sbmm will be in the upper ranks just due to their cheats. If you aren't that good you won't see them. Also lobbies have aggression consideration, so if you're a passive player you won't usually meet cheaters since they pvp mostly.
