A friend of mine, was a member of parliament in Iceland from the Pirate Party, he used to joke that Iceland should pass a law forcing Facebook to respect Icelandic values in what the moderate. Allowing sex and nudity on public content for all and restricting violence and horror.

As far as I know it never got beyond a joke. In theory he was in a position to do something about it but I doubt it would have been adopted as a law. He ended up getting sent around the world as a parliamentary representative for EFTA, the mini-EU alternative bloc of Iceland, Norway, Switzerland, and Liechtenstein.
