But are these regulation useful? Yes, they are.
When I was a teenager online - early 2000s - extreme violence was hidden behind obscure websites, not even indexed by search engines. I had friends who had "shocking videos" - think videos of actual killings - and I really tried to stay as far as I could.
In the past few years articles and publications regularly emerge that these topics and videos are now basically mainstream. After deep diving into instagram, tumblr, or twitter, to see if these claims are real, I'm going to say, they are, and this is very far from healthy.
We need some regulations; I'm only afraid they will be an overshoot, for what the chances are too high.
