Internet Security For Kids
The web can be a dangerous place for children. Website owners are generally protected against censorship, in the US, at least, by their freedom of speech. Preserving that freedom is important, but as parents, we don't want our kids visiting vulgar places on the web, or being exposed to pornography at an early age.
There are certain aspects of their personality that we would prefer remained innocent until they are old enough to know what the material is, it's purpose, and how things work in the adult world.
