If I witnessed a situation like this...

I would've immediately put those girls in their place. I would've explained how inhumane they were acting and that they themselves are ugly for talking bad about another girl. No one deserves to be harassed and treated that way. It is illegal, and morally wrong. The people in the show probably didn't feel it was their place to say something; but I know how it feels to be bullied. All it takes is one time to prevent someone from killing themselves. Victims of bullying may feel helpless, as if no one cares about their problem. But I do. I don't support bullying at all. This is something I'm very passionate about.
