Internet censorship & kids
Censoring the internet for kids in an automatic manor is a non-starter. It can't be done. I know ... I helped develop the network we now call "The Internet" ... It was designed right from the git-go to share information, not to suppress it. Even back in the mid '70s we were using what we now call "proxies" to get around filters[1] ...
Kids are kids. They are curious about everything. And as kids mature and hormones start doing what hormones are supposed to do, they start getting curious about sex. It is normal to the human condition, despite various holier-than-thou groups trying to suppress this normalcy.
The ONLY way to ensure you know what your kids are doing online is to watch over their shoulder as they do it. Harsh? Perhaps. But that's reality in The Big City that is today's 'net.
Note that I am not commenting on the right/wrong of curious kids doing curious kid stuff ... just that kids will do what kids will do if given the opportunity ... YOU did, right? Why are you surprised that your kids do the same?
