I believe the fappening essentially amounted to copyright infringement, since Lawrence owned the rights to the pictures. Deepfakes is a little more questionable, because it's a very strange topic. However, faking a nude photo of someone could essentially be considered equivalent to claiming "this person took a nude photo which looks like this", which, being false, injurious, and appearing in written media, amounts roughly to libel, I believe. But I am not a lawyer so those are poorly-educated guesses.
