Yes its under My Profile and its called Edit Ignore List - you type in the members name ...this is under Settings and Options. I've only used it once and don't really find it practical for me but its probably good for others. The post will be blocked but you have the option of clicking to see if you want and since I'm a curious person I do that ...which is why its not good for me lol. You can also block whole forums for those who are triggered by those forums...for example the abuse forum. Hope this helps.
