P2P is the place where porno files are at their most accessible but the "Clean feed" won't even touch it. The problem is when the filter starts touching on areas which the Australian community finds acceptable.
Two examples I can think of.
A world renowned photographer had taken some nude photos of a young girl. He did a private showing at a gallery. One of the invited people took exception to the images of the young girl and made a complaint. The tabloid press grabbed the story, accused him of being a pedophile. People came out ranting and raving how could this happen. The photos were taken away by the police, the artist was questioned.
The photos were taken years before the showing, her parents gave him permission to take them. The girl, who was years older, gave permission and her blessing to show the pictures. The police gave the photos back to the artist because he didn't break any laws.
I did get to see the photos. They were very striking and beautiful and had no sexual connotations what so ever. The problem is, one of the biggest criticisms came from our Prime Minster, who said it was disgusting and horrible and these types of photos should not be called art, even though he never saw the photos. There are now some state laws where you need permission to show some types of artwork.
Artwork which is acceptable around the world and by our own laws can be filtered out
Another example is that Australia doesn't have an adult rating for computer games (its the R rating here). Some games have to be changed to be accepted into Australia. Although the gaming community have been screaming out for an R rating the government have refused. We can watch violent movies just can't play violent games.
Now if a game is refused classification because we don't have the R rating, the board could filter out web sites which show information for that game. After all, its the same people who rate the games who will be rating the web sites.
They might not end up doing this, but how would we know, if they will not tell us which web sites will be filtered, and the reason why.
