Nope. Blisting in this game isn't really good at all lol. If you was married through eternal bond, and you threw away your ring, he can still use his to teleport to you. He can still send you mail but you cannot send him anything as you've deleted him of your friends list (stupid huh?), you'l still end up in the same duties if you so hapen to queue for the same thing at the same time, only thing is, you cant see what he's saying but he can see what you're saying. As Ilea has stated, all it does is grey out the parties he posts on pf. thats it.

All i can say is just ignore him if he causes any trouble.
