It would be useful for many reasons, if it also had some options to toggle on/off, for each player:
- block them in the forums where you never see their posts
- block them from wall posts, where neither player can post or view on each others wall
- block them from game play, where they won't show up in any game you are in
It would be a welcomed upgrade even if there were no options and a block automatically handled those collectively. But I'd prefer some options built in to it that are user defined.
