Block the ones that send them. That's what I did. I never see a chat room invite since I did that.Freaking n00bs and hacking n00bs on Xfire keep inviting me to a chat when I don't wanna be invited. Some spammers too. I'm in that Flyffteenagers clan or whatever one of the 15 Days Of Fun clans are called.
