Even Simpler Solution...
I heard a while back that the US Government had the rights to all those p2p file sharing networks and they managed to kill five of them (sadly) in one day.
What it means to me is that if they US Govt wants to they could kill the On-Line Porn industry in one fell swoop, thus negating the majority of any searches for a porn related image, video or story, whatever form they appear as, by any teenager or sad, lonely, adult without a real girlfriend/wife etc.
If the liberalists out there want to go looking for porn, let them find it on dodgy vid sellers in the centre of town where they should be.
Paris?...because she's a person and not a sex object
