Bingo! If FB trains to recognize the face of some friend of an FB user, but that friend is not on FB, and never previously signed up for FB, then FB would be clearly in violation. I think FB does this when people tag friends? I'm not sure though? You upload a pic of a night out. Tag all your friends in it. And one of those friends is not, and never has been, on FB. Well, clearly, that guy never gave FB consent. And FB is doing it all without his knowledge.
