help.vrchat.com is supposed to be the point of contact for reporting players if the in-game (self-)moderation and user reporting features aren't enough, but the site doesn't support SSL, so confidential information can't and detailed logs should not be provided there.
Upon visiting the website, browsers complain that the certificate is only valid for *.happyfox.com and when accepting the risk to visit the website anyways, you're being presented an nginx 404 error page.
