UK lifestyle blogger Hannah Witton did a video about the UK plans for a porn ID. One of the proposals, besides using drivers licences and passports, was the ability to purchase a porn pass from newsagents. It also won’t of affected social media sites like Reddit. MindGeek was/is going to paid by the UK government for it’s age verification software. MindGeek also owns many of the world’s most well known porn sites. MindGeek can also sell their age verification software to other sites.
A VPN is also a good way to get around age verification.
