Cloudflare works with the UK government to facilitate blocks within their infra, I assume in exchange for being allowed to access UK network infrastructure.
In the case that a blocked site resolved to a Cloudflare IP, it would likely be kicked off of Cloudflare, or geo-blocked for UK users (by Cloudflare).
Ironically that url is forbidden for me, I was under the impression that CF were fairly anti censorship, or at least they inferred that they should not be the one calling the shots (in reference to kiwifarms)
