@silverwizard that's a toughie, for those of us not used to hacking the system like that. Can she screen shot the threats, with date and time and user name, then block that user and see if the same threats show up under another name? That should at least be a start for FB, to show there's a pattern. Proving who it is, though, that I'm not sure about. Can she explain why she thinks she knows who it is? That and the screen shots might be enough to have a conversation with a lawyer.
