Nothing is childproof.  

More seriously, I am absolutely against any kind of content filtering on both technical, legal and moral grounds. And that's a lot of boths!


Techinical: everything should be encrypted, the system shouldn't be able to determine the content anyway.

Legal: when you allow some things but not others (or try to) you lose your common carrier status and become legally responsible for said content.

Moral: fuck censorship.
