Internet services are designed to be addictive for kids (and adults). Usually, this addiction is not good for the kids. That’s why my kids are not on the Internet unsupervised.
I don't have kids, but there's a part of me that would want them to see the bowels of the internet, and hopefully Never want to see that crap again. I know there are pictures I wish I never saw. I'm so glad I didn't see the toddler whom was raped by a Russian soldier. Putin arrested that soldier I head.
If I had children, I don't think I would let them use the internet either.
I wonder if their are any good studies on letting children have free access to restricted. Maybe the study couldn't even be legally carried out?
