For some games like dota 2 cheats only make them marginally better at the game but much more frustrating to play against. The most common cheats are map hacks and instant action scripts both of which can be useless without the game knowledge for correct play. But both of these cheats make playing against them frustrating but they wouldn't rise to the top.
Again I think there’s a better way if we push through the concept of a fair game, and just focus on fun. It should be possible and accepted to block (and never match with going forward) players who are just… unfun. Annoying, poor sports, or cheaters. Heck, maybe player-curated and shared matching and blocking lists could become a thing.
Games are a social thing we do to have fun, there’s no obligation to spend your limited social free time hanging out with annoying people.
