The data quality here seems poor, eg it lists reddit.com as having shut down, which is clearly false. I think some list like this would probably come across better with some curation so it isn’t largely a list of unsympathetic porn sites and no-name blogs being blocked to spite the UK.

Under the main link (the big, bold one) there is a link to what precisely has been blocked. Apparently, it's enough for them to just geoblock specific subreddits, like: dark humour, bowel surgeries, some porn stuff, etc.
