We could think up some extra phrases here that people might actually use. I had fun thinking up a few last night.
Usergroupid 9. I don't have one. It was a custom usergroup which I've deleted. The hack therefore just set users to usergroup 4 (COPPA/Users Awaiting Moderation).
The problem with the usergroup 'Banned by Moderators' is it's created when a moderator first bans. If you've already added usergroups prior to that then the usergroupid for it will be different. If you don't add any usergroups then it should be 8. At least I think that's how it works.
