Where are these rank teenagers who bash one out in Starbucks? And why would they bother when most 3 year olds know their way round a parental lock at home?

Seriously. If any teenager today doesn't have the tech savvy to bypass an adult content filter in their own home, then they have bigger problems than porn. Such as the fact that they will never have a job in the modern world, by virtue of being technology-retarded.
