Being a redundant problem user will get you revoked, such as hordes of evidence that you are joining servers specifically to spam the chat/bricks just to be an idiot.
this is old but it's incorrect. being a general problem user and/or spamming bricks/chat in game (both are easy to prevent or stop) will not warrant you a key revoke, you are not damaging the structural integrity of the server(s). this is why we have a kick/ban function. if everyone got revoked for being a problem user the new ids would still be in the 30-50k range.
iirc most key revokes are due to billing problems, and that in itself is a minority so i dont think any user, giant troll or otherwise, should have to worry about their key getting revoked.
