Responding very late to say it’s called MonsterQuest - sorry, I thought giving the name would violate the rules of this lemmy instance. (is that the right terminology?)

Ah, thank you! That makes a lot of sense. I’m broadly familiar with CDNs, so I figured they must all be using the same database, but I never made the step from that to “the sites themselves might have the same owners”.

I’ll keep that in mind, but it is not an answer to either of my questions.
