I would not be surprised if there is some P(controversy | viewing user, time elapsed since original flagging) metric, and when it goes below a threshold, certain non-prestige or international ads can be shown - ads not likely to cause any problems.

Because someone, at some point, got an email that looked something like https://www.justice.gov/d9/2023-09/416421.pdf (via https://news.ycombinator.com/item?id=37572692 ) - and one does not simply see an email like that and not implement this kind of thing.
