I agree that self-policed communities seem like the best solution to the general problem.

For example, public Minecraft servers often get harassed by cheaters and griefers. Some servers try to circumvent this with all sorts of complicated anti-cheating mods and moderation tools... but ultimately the easiest solution is to just have a whitelisted server with only people you trust. This tends to work better because every player is accountable, and has the bonus side effect of fostering a community of people who actually know each other.

Private, moderately sized, self-policed communities really do seem like the only sure-fire approach to avoiding cheaters in online multiplayer games. Otherwise it's just a constant cat-and-mouse game with the cheaters usually coming out on top.
