If an image references rape directly, it should be tagged with ’rape’
That includes text-only "images" talking about the subject.
Please understand that this site was created, is funded and operated exclusively by volunteers; we physically cannot monitor every upload, and our tagging rules do specify that anyone can add tags that are correct and relevant.
@The Smiling Pony Does this also apply to "9/11 never forget" images and anything that mentions "Cupcakes"? In my experience, that standard has only been applied to rape. It seems to me that the tag should be for depictions or vivid descriptions of grimdark things, and not just for brief mentions of something grimdark in the abstract.
The safe tag doesn't mean "safe for work", nor even "safe for an average functional adult". It means, very specifically, "safe for children, in the manner of the show". Yes, this excludes discussion of anything sexier than Rarity's unserious flirting or more violent than unaddressed mean-words bullying or consequence-free cartoon knocks.
You have "suggestive" and "semi-grimdark" for anything over that line (but only just). Things that could be OK at a workplace or a topic for well-behaved discussion.
