How can you find out who blocked you on facebook?

What applications can I use to find out if someone blocked me on Facebook (or view their profiles)?

• I am looking for facebook applications that will tell me if someone has blocked me. I heard of an application called FindXFriend but it appears that it is no longer available. The reason is I want to know if the person even has a profile or not. Also, are there any ways to view profiles that have blocked you? I have someone that has and I believe they might slander my name with false accusations. I attend a graduate school and I do not want my reputation to be ruined by lies, if this is the case, I want to be able to report it to the dean for disciplinary action.

• Answer:

  The easiest way to determine whether somebody has blocked you is to request them as a friend. This will have one of three results. You will be told (a) This user is already your friend (b) This user has to approve your friend request (c) This user has blocked you As Facebook is strictly a leisure activity, your problem will be of no interest to the dean of your graduate school as he oversees conduct and activities only within the school
