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 don’t know how technical you are but its impossible to block kids from watching pornography online without implementing a draconian system in which we all loose our privacy . First there are millions and millions of websites with different domains that have thousands of pornographic videos and photos. Plenty of companies offer adult block content but there is always a way around. If they ask for ID , then a market for fake IDs will show up. This is like scams from India , Nigeria , and all those countries that are calling to scammed you. Its impossible to stop it and the only way is to create awareness and educate people on how to prevent it. So the same with porn , block it as a parent and try to explain why you are doing it and the consequences of excessing watching it.
