True. I don't like those things among the submissions of my jam, but after a lot of back and forth with jammers about that rule in previous jams, I have decided to put the bare minimum criteria possible that I can tolerate and that one is the very bare minimum. And so for the examples you gave, all I am going to do is to discourage you from putting such things but if you do so anyway I won't remove them. I will let you know that even with this bare minimum rule I still have some people complain that there should be no such rule entirely but this is what I have decided on but I'm not going to budge on that.
If you have noticed, most of the rules of this jam are on the looser side from what is expected or what I personally find comfortable (such as the bare minimum criteria for magical girl) and that is by design, and this includes the NSFW rule. I hope you understand.
