No clue, we'll have to wait until someone leaks it here or on kemono/neko, but I guess it's a "testing the waters" question, to see how forward they can go with certain type of content and since it's weird for them to ask anything related to scenes my guess is that the question is related with some more controversial content (Lesbian, a more hardcore kind of ntr, flashbacks with other people, non-consensual, gay, voyeur, etc.), and based on the answers also know the percentaje of their subscribers interested on that kind of stuff and how far they can go without losing too many supporters.
