The real dangers aren’t dedicated porn sites, but poorly managed social media sites. You can’t just block the domain.
In many cases, the bad material comes from peers. Kids have always talked about “bad” things, but the internet super charges it.
I generally support these efforts, but I’m also very cynical they help.
Politicians focus on the problems they control, like rules for sites that rigorously follow the laws and fit in a clear category. They care far less about the grey areas where the most harm is often done.
I think this is a good thing. I’d feel a lot better if these efforts were combined with rigorous privacy protections.
For example, third party identity verification services should be civilly liable for privacy breeches, and required to carry insurance to meet the obligations.
