There are a lot of GOP-controller legislatures in the USA pushing through so-called “child protection” laws, but there’s a toll in the form of impacting people’s rights and data privacy. Most of these bills involve requiring adults to upload a copy of their photo ID.
I agree with that statement for adults, but not for children. Even if you’re talking about something like drugs, protecting kids, who don’t make rational choices, is important.
This is the issue at hand: How do you prove it is an adult and not a child attempting to access the content?
Solutions exist for parents to block/allow access to content on routers, cell phone plans, and devices. The government does not need to impose here.
