Ashby is not a champion of free speech in Australia. He publicly made false allegations with the intent of destroying Slipper's career. Seems like a straightforward case of defamation. I'm ok with having a law to protect against this sort of thing.
Back on topic - the internet trolling stuff is ridiculous! Farah needs to harden the fuck up. I can't believe a footballer would be such a princess. I doubt there will be any anti-troll laws either. It's just talk to try and get political advantage at this point (doubtful whether the NSW or federal governments are succeeding).
