Putting aside the porn issue, the privacy concerns here are enough to make any sensible government set this policy aside. Giving porn companies a large database of the personal data of a substantial portion of the UK population is not going to end well. There’s also the issue of effectively restricting access to something that is legal for adults, and the fact that any site that has content that is below a threshold of 33% is exempt. It’s just such a poorly thought out policy.
The idea that this will protect children is laughable.
But my favourite bit of today’s announcement is that the department responsible for this broke GPDR rules by sending out an email with the recipients email addresses visible to all.
