"don't favorite, this is copyrighted" (ok, I'm paraphrasing)?... erm, considering how favorite-photos works, and considering that _every_ photo that isn't public domain is (c) by _someone_ (usually by you, if you have legal right to it, but of course so many people here use images illegally and think nothing of it- but that's a subject for another time) - anyhow, that would remove that favorites feature entirely, if that reasoning I read made any sense, which fortunately it doesn't.
