As I'm using this website to post a novel and am considering writing a web novel specifically for here, I've started looking more closely into the rules and processes and I realize the Mature content tag is very very loose. Taken very conservatively a slap to the face (violence) or a kiss to the cheek (sexuality) should be tagged as mature. Taken very liberally it doesn't need it unless someone gets horribly mangled in graphic detail or there is some kind of penetration. Obviously, the line is somewhere in the middle, but how do you decide that?
My book has a lot of cartoonish violence and some mild sexuality/nudity. For example, the heroine barely escapes being attacked by a monster and needs emergency medical attention. There is blood and bleeding, but no real description of the wound. Monsters that don't bleed are frequently destroyed. Even people are killed, but it isn't graphic.
I'd like to be on the right side of the content policy, but there are many disadvantages to marking something as mature. Not only do you get less exposure since you can't be posted on the app, but anybody that sees my novel and thinks it's edgy because it needs to be marked as mature will be sorely disappointed when they actually read it. Plus people that don't want graphic sex or violence may not give it a shot, even though that's not really a part of the story.
