As a father of three young kids the thought of child porn disgusts me.
If only an Internet filter imposed by the government would be effective against it.
As a professional software engineer I can't help but acknowledge that the proposed filter will be 100% ineffective at stopping child pornography and that hundreds of millions of dollars could be better spent elsewhere.
The proposed censorship by senator Steven Conroy does not propose to stop most material that is unsuitable for children and it does not propose to stop the most common channels of illegal content on the Internet (bit torrents).
Finally any VPN will effectively go straight through the filter so anyone who wishes to can circumvent it using current technology.
