As much as im all for for personal freedom and I don't like to see goverment influence ISPs - in this particular case I'm all for making adult sites harder to access via paywall or whatever. There is nothing good about porn being freely available to everyone, especially growing up kids. Porn simply destroys families, lives and relationships.
