Something that has come into the media in Aus recently is bullying on social media.
The debate is mostly around what is acceptable to say to/about someone and what is going to far?
The other part of it is should the bullies be named and shamed?
I think it's ok to say that you don't like a particular song/show but I don't really see the need to tweet or facebook the artist just to say that. I think that you can disagree with a article, as long as you can say why. Suggesting someone should harm themselves or whishing they get hurt is not acceptable.
As far as naming and shaming the bullies I'm not this is the answer. It could result in them been bullied. Seems to me that we don't punish someone who beat up another by arranging a beating for them. So would inciting bullying against a bully be right?
You could fine them or ban them from the interenet. I imagine there are ways around this though, unless you are been watched constantly.
