Who's blocked you in FaceBook?

Today i was looking at my friend list and saw some friends gone missing.When i saw some people with unknown profile picture: 




This raised 2 ideas:

1-The user have deleted me
2-The user shut down the account or FaceBook banned it! 

 If you're looking for a FaceBook plugin or application to show who deleted you,you're on the wrong side.

 Just look at your Friend List,it will tell you everything!
