I feel like this whole problem is just made up. Back in the day, when I played lots of Counter Strike, we had community servers. If a cheater joined, some admin was already online and kicked them right away. I'm sure we hit some people that were not actually cheaters, but they would just go to another server. And since there was no rank, no league, no rewards (like skins, drops, etc.), there was no external reward for cheating. It annoys me that cheating in competitive video games seems like a bigger problem than it has been in the past for no good reason.

Manually managing one cheater in a 20 person server is obviously very different than managing games between multiple millions of concurrent players
