It means that patreon only ever makes a paltry effort to look into such things and unless someone reports any project with rape in it will probably get away with it. Case in point Milfy City and basically every game similar to it had or have scenes in them in which hte player character sexually assaults his potential partners while they are asleep. Milfy City, during a period of extreme lack of activity and only one release on over two years, was reported and forced to remove that content, but prior to that it had been in development for a few years and no one said anything about it. Incest isn't allowed either but quite a few games feature it as part of the basic content for it and until they get reported it isn't removed and replaced with "roommate" or "landlord" nonsense. There's plenty of leeway with patreon and most of it centers around whether or not patreon is looking.Didn't Clionha coerce rowan for hypnosis/sex. Isn't that essentially rape or at the very least dubious consent? Besides I think the patreon guidelines say you shouldn't glorify rape and that lolita is allowed on there? So, shouldn't it be fine so long as you don't glorify it
Edit: now that I'm thinking about it, you have a bunch of scenes in this game that are basically rape, so I don't know what you are talking about.
With that in mind you can't really make the kind of game SoC is without having some despicable situations and straight up violent rape is not a thing that the main cast gets involved in. There's coercion, yes, but it rarely goes past that and basically every character not named Jezera or Andras who has a large sexual role is the victim of it at some point. You'd lose out a lot of content if everything was purely vanilla. Pretty much the only storyline that could reach its current level of completion would be Cla-Min's at this stage.
