> And how thoroughly is that prohibition enforced? Do you scrape libgen, for instance? Coursework on university websites? Mathoverflow? No idea, I'm not involved with that effort.

And I saw questions get banned for being, at their core, too similar to leetcode ones (despite not having the same problem statement).
