UK porn ban: What is it, when does it come into effect and can I get around it?

The UK is about to introduce restrictions on watching pornography of a kind never before seen in the world. The government is planning to stop children being damaged by watching adult content by stopping anyone from doing so unless they go through a "rigorous" age verification process. Websites that aren't part of the blocks could find themselves being punished or blocked entirely within the UK. We'll tell you what's true. You can form your own view.
