Yeah, their go-to is to cite Patreon saying that intergenerational incest is against their rules, so basically any parent/offspring incest. But it really doesn't hold up considering there are other games that either get away with it, or successfully moved to another platform. But they pretty much only care about the money, so they won't do anything to jeopardize that. I don't get Patreon's logic there either, seems if you are going to ban incest, you would ban all forms of it. Sibling incest is the most common, but it seems they are perfectly ok with that, hence the plethora of it in the game.
