volunteers which aren't necessarly pro player and cant distinguish good players from smart cheaters.

The developers aren't pro players either, the cutting edge for anti-cheats still require that non-cheaters play with cheaters for months. I would not be shocked if simple vote-kick outperforms every anti-cheat on the market.

A simple vote-kick will kick, will kick so much players that doesn't cheat. It's already used to troll in games like CS.
