"Add Foe" is a valuable option, but it's not that effective. The only benefit is that you can't see that persons posts.That guy can still PM you, right? Can't we have this feature enhanced to the extent that this "Ignored" person can't bother you in any form, like FB.
It should work the other way around, too. I mean, if I remove Mr. Ass from the list, everything should be normal.
What's say?
