PCs are such tame beasts that it only takes a relatively simple piece of software to be installed to vanquish those nasty pictures of naked women to the online ether. Parents who complain that their kids know more about computers than they do will need to learn, at least to the point of securing access to the family PC. A good analogy here would be satellite and cable TV. Adult channels are readily available, but require a viewing card to be inserted before the pictures will unscramble. Parents don't complain that this process is beyond them, and no one else can complain about the erosion of civil liberties.
