I don’t know much about anti-cheat development, but it can’t possibly be that hard to at least implement something that checks whether a player even could have done something in a certain amount of time which would eliminate a lot of speed related cheats, and for the rest, why not look at data averages to try to weed out cheaters?

I know combing through the data is probably complicated, but so is installing kernel level anti cheat software that has to monitor every single process running on a person’s computer.
