I would assume it's like the A&N stuff where it's (reportedly) all people reporting and DMing each other in private. If you're just a normal user posting, you have no idea about any of it until the jannies come in one day say "Y'ALL CAN'T BEHAVE! SO HELP ME, I'LL TURN THIS SUBFORUM AROUND!" and 90% of people wonder what all the fuss is about.
Either that or it really is a matter of equating even the most innocuous conversation with "she was Almost Raped™!" because I sure as hell am not seeing all these beyond-the-pale death threats and rape threats and so forth.
