Whether or not you use 'em, VBulletin has social groups ( http://forums.toucharcade.com/group.php
) which basically act as mini forums within a forum that can either be public or invite only. Many moons ago spammers attacking the forums decided to go for creating thousands (no joke) of social groups for streaming soccer, male enhancement, and all the other junk that gets spammed. So, we ended up deleting all of those and just turning off the ability for people to create new ones.
I just turned it back on, so, if you've been waiting to create a social group, you should
be able to now. Additionally, mods don't really pay attention to stuff that goes on in the social group side of the forums unless someone reports something... So if you're a social group user, please let us know if you start seeing a massive spam wave again. Hopefully we can cut 'em off at the pass before we reach "MOTHER OF GOD!" spam status.
