Heal has gotten a bit legal with forum writers in the past (Sydney guy re allegation of a racial taunt). Keep in mind that if he comes to me with the right police/court request, I will need to comply and pass on enough information that would allow him to force your ISP to identify you.
I'm also not sure if truth is considered a valid defense for defamation in Australia.
If you've written something here that you'd like to retract, you can contact me.
For now, I've cleaned out some comments that are clearly crossing the line. I don't care if you think they're true, you will get yourself into strife mentioning them. If you want to discuss them, you're welcome to do it elsewhere but I'd suggest finding a lawyer first.
