Funny, when people copy music online, it is assumed to hurt music industry. So... to stop people from producing more child pornography, it should be enough to copy existing one as widely as possible, no?
Anyway, what happens in US is crazy. Any picture of naked child is immediately child pornography, and used as an excuse for more spying.
As a bonus, here's picture of one-year-old trying to make love with 6-year old. No children were harmed while producing this photo.
