What legal trouble can someone get in to for making a fake facebook with someones photo?

They could sue you for some kind of Libel. But what you are doing is essentially fraud and that can carry a penalty too, because you are essentially impersonating someone else. And you would not be asking if A. You were not thinking about doing it. OR B. you had already done it, in which case this question is enough evidence to prove it. We are not as anonymous as people think on the net.
