Cheaters ruin games. Anti-cheat sucks for privacy, and is ineffective to a point. As long as there are tryhards willing to shell out a few $ to have a leg up on the opposition, there will always be someone willing to code a way to make it happen. Even statistic-based anti-cheat is an utter failure. Not sure what the answer is.
