Bad idea
Clued people like myself and other Reg readers will know this isn't true, but as all pollies know, you can fool most of the people most of the time and that's usually enough. How easy would it be for Mr Rudd and Mr Conroy to point to the attacks and say "Look, this is a type of e-crime! Our filter stops some types of e-crime! Just imagine if that was your web site - and don't forget if you're a business you make money from your web site! You need our filter to protect your job!"
The proper way to stop this filter from happening is to dress up in a white lab coat, stand in front of a server farm and tell the Australian public that 1) it won't work and 2) it will make the internet crawl. Then tell them to write to their MP. Especially if their MP is one of the two holding the balance of power.
Paris because she's smarter than Mr Conroy.
