Clearly, rather than take responsibility for the raising of their own children, the only recourse is for parents to sue everyone. MySpace is only the first stop. After that, it's clear that Tim Berners-Lee should be held liable for inventing the Web, the telcos should be held responsible for carrying the traffic, DARPA should be sued for inventing the Internet, Cisco, Juniper, et al. should be sued for building the equipment that allowed the traffic to be carried, MySpace's colocation facilities are clearly responsible for housing the vile site, and finally the rest of humanity as a class should be hauled into court to face the music for not preventing the little Julies from falling prey to these molesters.
Nuke the site from orbit, it's the only way to be sure.
