How to block all Medium-based websites in Kagi and uBlock?

Question

I have blocked Medium in my Kagi search results but there are numerous other websites with custom domains that point to Medium under the hood. Is there a way to block all such things? How about in uBlock?

in uBlock Origin preferences, -> My Filters -> add:

    ||medium.com^

That should block their site and all the sub-domain custom domains that point to it. [0]

As for blocking domains that point to it without using "medium.com" in the name, that would likely be a never-ending process of whack-a-mole, I think. They use CloudFlare and blocking CF's CIDR blocks [1] can certainly be done but then much of the websites on the internet would be blocked.

From my tests with an random medium site it isn't possible. The site has set the A-record to the medium ip addresses. ublock origin uses the detection of cname records. For filtering my search records i use ublacklist.
