I love the idea of anti-cheat that doesn't just ban cheaters, but messes with them and makes them waste their time

This actually sounds like a coverup in an SCP article.

"At 1700 hours the foundation became aware of an unknown digital entity in the video game Call of Duty: Modern Warfare 2 that would only make itself aware to cheaters. Foundation assets within Activision has announced this as a new anti-cheat system."

They really decided that Naruto was right and kage bushin no jutsu is a fantastic defense against rapid attacks lol. That's really fascinating. From the POV of a normal character cheaters are like storm troopers missing their shots over and over again and opening themselves to be sniped. From the POV of the cheaters their opponents are really dumb grouping together like that. I wonder when cheaters will get savvy to this technique and just move house when they see too many targets in a space.
