It is disappointing that they went to this hassle but apparently didn't read the first link that comes up when you search this:

https://www.legislation.gov.uk/uksi/2025/226/made?hl=en-GB

Tl;Dr at the most stringent you need at least 3 million UK monthly users. Depending on what your site offers in terms of functionality it then allows 7 million or even 34 million UK monthly users before you need to care.

With respect, I doubt this blog has 3+ million active UK viewers. This legislation is designed for Facebook et al, not for random personal blogs on the internet.

But hey it's a free world so if you want to take the moral high ground go-ahead. Just be sure you understand first :)
