Yeah, I've noticed that I've been getting a lot of invitations lately from random people to there "Fan groups" Even though they have done completely nothing with their life to have fans. I thinks its more for the sake of trying to have the group with the most members.
Yeah. I accept every invite I get. Plus, I'm a groupmin. I go and read through all of the shouts to see if there's anything bad in them, daily. I actually don't get as much spam as you'd think.
