Just a quick FYI, people:
This ban is aimed at violent porn, not porn (as in naked people having sex). So, just to be clear, images depicting naked people having sex will be a-ok, whereas images depicting, say, women being raped or abused would not. It's the consenting adults principle, if you will.
How do I know this? Well, first of all, it's in the article: " "We have to be able to discuss a ban on violent pornography, which we all agree has a very harmful effects on young people and can have a clear link to incidences of violent crime," he said. " The "he" here is Ögmundur Jónasson, the Interior Minister. Also, he's discussed this on his homepage (which is in Icelandic, but here's the link: http://www.ogmundur.is/fra-lesendum/nr/6571/) where he specified that his concern is violent porn, NOT porn itself.
That said, I'm pretty skeptical about this being possible in practice, but I'd love to hear Slashdot's opinion about if people here think it is.
