Personally, I'm more worried about what they're asking for a solution than her crying out because she's being virtually harassed. Cyberbullying is a huge problem, and its bad regardless of who you are. But demanding legislation? She wants facebook to regulate what's being posted on their site. What she wants is censorship. Who decides what's considered demeaning? There are things that you can say that are clearly, w/o a doubt, demeaning. But people post stuff that gets taken the wrong way all the time. No one should have to have anxiety for posting their opinion, b/c repercussions are now a lot more serious.
If her life is truly in danger, and she could very well be, that's why we have law enforcement that protect potential victims if they feel threatened. That's what they're for. People are always being stalked, harassed and abused, its a constant problem.
