From time to time it seems like Yahoo likes to delete groups for no reason. Also if you search their directory you'd think there were no groups. They do not list the adult groups since like 2001 or so.
Since 2001 or so?
God, it's hard to believe that it's almost 2010, time flies, doesn't it?
So many ballbusting/femdom websites are still old-looking like they weren't updated graphically since 2001, such as thevalkyrie.com and goddess club (not that these sites are bad)
