Hmmm.
I haven't read or posted fic here for a long time, but I am surprised if there really is a tendency not to warn for things such as rape or sexual assault. It's not about 'spoiling the story', or 'protecting' people; it's that, as I've learned elsewhere around the internet, people who have lived through rape and assault can find these kind of stories triggery, and they prefer to know in advance that a story contains a scene or scenes like that so that they can avoid them.
If people don't want to be explicit about the specific nature of the scene or scenes in their fic because they don't want to give spoilers, why not include a statement at the start along the lines of
Contains elements which may be triggery for some. Please IM me if you're concerned and want to know more.Wendy
