FB already has shadow profiles, because its Like/Share buttons on sites can track people across the web, I wonder if knowing the person's face/voice is useful.

They probably already know if a shadow user is most likely a teenage male (visits gaming sites) or middle-aged lady (hmm, what sites do they visit?). I guess using facial/voice profiling would be a way to confirm the profile.
