Too bad it's not actually anonymous at all.

You can easily identify anyone by viewing the source of their FB pic. For example:

  http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs444.snc4/48985_665523839_4409_q.jpg

profile ID is 665523839, which you can plug in to see all their details: http://www.facebook.com/profile.php?id=665523839
