For what I expect are similar reasons the list of forbidden image and text content gets so detailed:
5.0.6: No visual content depicting executions, murder, suicide, dismemberment, visible innards, excessive gore, or charred bodies. No content depicting, promoting or enabling animal abuse. No erotic or otherwise suggestive media or text content featuring depictions of rape, sexual assault, or non-consensual violence. All other violent content requires a NSFW tag.
I now know from this list that posting Hieronymus Bosch's "The Garden of Earthly Delights" would be problematic even though it wouldn't occur to me that medieval illustrations of fictional torture would break the rules. And I now no longer know whether this instance considers the usage of variously themed slurs as against the rules, especially in contexts where they're not direct personal user attacks.
What is socially acceptable obviously varies widely from culture to culture, and definitely instance to instance. The brief list from the previous version helped me to identify the overall culture of the instance to figure out if I would be welcome here. Now instead I'm just not sure if a sweet Aztec decorated human skull from c. 1350CE is allowed because it is half literal human remains, half turquoise, haematite and gold mosaic.
I appreciate that finding the balance here is very difficult. It may just be because it's late and I'm tired, but I feel less certain about what the expectations are with this version than I did the previous. I hope you will consider returning a bit more detail to section 5.
