Hiya, this is a great question, and something which I will have to clarify in the FAQ/beginner’s guide next year forward.
I have had these hard blanket rules for a few years for several reasons which I won’t go into in too much depth; but partly it was to cut down on screening entries (this is a 1 person effort), to avoid certain types of entries which glorify and/or sexualise certain subject matter which I have a personal hard no-thank-you attitude about (such as incest), and avoid having both myself and any entries be subject to the recent harsh guidelines toward nsfw content as a result of recent payment processor’s pressure on platforms hosting this type of content due to legislation in different countries (my own included.)
I am aware that the hard-no’s are a little hypocritical, given that other serious and horrendous subject matter which is risky is A-OKAY to have in entries (murder and all of that other stuff…) But for now, I will say that this entry wouldn’t meet the rules despite the nuance on the subject matter as it is a hard rule. You could revise the idea a little, or submit it to another yandere/dark romance-esque jam (I think Stained Red will be running again and they have different rules from this jam.)
Hope this helped give some insight! <:)
