I'm no prude either, but the problem with the site that the OP linked to was that it had child porn on it. If you think that's okay, whatever.
I never said child porn was okay, did I? There's so much porn in the world, it's not worth getting "your knickers in a bunch" over. No amount of rules or legislation is going to stop it. It's like the FCC trying to prevent curse words from going out over the airwaves. Just give it up. Everyone has said or heard almost every curse word in the human language. What's the big deal about hearing it over the fm dial?
