I've been thinking for a while that it should be mandated that any of the "infinite scroll" websites should have to be able to explain in plain English why they show you any particular item, including ads. "The advertiser gave us a list that has the email address you used to register." "You are a female in Orange county between 24 and 26." "This is a post from your friend presented in chronological order." "Tom from your uploaded contacts clicked on this ad." And if they can't explain it, then they can't show it. So "our opaque neural network decided this" doesn't cut it. Kind of like how you can click in the tip-right corner of a Facebook add and get a very obtuse explanation for each ad.
