Hmm, I was starting to think it was just me.
I'm fairly new to city of heroes, but I've played several other MMOG and although the community is (in general) much more welcoming than any other game I've played I've *never* had so many blind invites. Even in WoW, famous for it's [censored] collection you were almost certain to be contacted first. Blind invite spamming ususally got you labelled as a 12 year old and ignored.
