It is pretty common for scammers to take someone's photos, perhaps even altering them slightly, then creating Facebook pages in someone else's name and inviting all of the real person's friends (from their friend's list) to "friend" them. I'm not sure exactly what the scam is but I suppose it has to do with getting information from someone who thinks they know you, or are related to you. I have had several friends who have had their Facebook pages cloned. When someone cloned my younger brother's page, he warned us not to "friend" the fake page, so I told him that the chances were that the imposter was nicer than he was. That's one of the things that frustrate me about Facebook - you can never get back to a page once you move away from it.
