Social Group Spam

[Panzer Max]

Hey guys, we've been hit with the latest thing in spam--members join and create social groups, then spam them with messages. I've seen this in other forums, and so far, no one has provided a smart way to delete all the discussion messages and groups. Sure, I could do it page by page, but some of these groups have 3000 messages. I would like to try deleting them in the MySql database, what tables would the Social Groups discussions be in, so I can be sure not to leave any orphaned messages or discussions, before I delete the Groups.
