Tracing Facebook hacker with Accounts permission.?

[BrokaToe]

That is for sure a serious invasion of privacy. The best thing to do is to go here facebook.com/hacked
there are steps laid out on what to do in this instance. As far as tracking the criminal down, I wouldn't put too much hope into finding out exactly who is doing it. Proxy servers are all too easy to come by and I'm sure this person is probably using one. Also would probably be a good idea to use the https://facebook.com instead of the http:/ from now on, it they are not already using the secure server, they should be. This probably isn't much help to your question, but a defensive action is probably the best first step in this situation.
