1) The game or service is auto-banning players, not the community.
2) Player fingerprinting isn't CPU-only.
3) The hardware aftermarket contains every flagged component without exception.
The aspect I have a hard time wrapping my head around is the amount of money people will spend to cheat in a game for a limited amount of time. Simple account bans are useless against people who have no problem buying another copy, forever.
From my perspective, the unusual part of this claim is that OP's community hasn't gone invite-only like so many others. Open servers are a labor of love.
