I am sorry if this not the right place for posting but I have to figure this out.
Suppose the following scenario:
Someone sends you a message on Facebook, a registered person, not eventually your friend. Obviously he is using false name and a fake photo. What are the chances I discover anything even though trivial about this person, I have many things in my mind : IP address(which may be a dynamic one so nothing interesting for me) or something else, any piece of small information would be of great value to me. It is not a joke so I am committed to discover what happened. If anyone comes out with any ideas please feel free to post them.
Thnx in advance
