As above, I try to rate innocent nudity Q. But there's a subjective borderline there, too. If it's a photoshop where someone took a fairly innocent image and stapled a vagina on it, I can't see any intention but to make it porny, and I'm more inclined towards E (even if I might not have been if the actual artist had drawn it that way). I also try to be a bit conservative for loli stuff.

A lot (not that I clicked all that many) of these are suggestive + full nudity, which I think is reasonably E.

I think if vaginas are the dominant bodily feature in an image, like a big arrow pointing and going "this, here, is the purpose of the image"--then it's also reasonably E. Post #54245, post #44197 make me think they're saying "hey look, poon!" Many of them have the rough, out-of-place, photoshopped look to them.

On the other hand, post #47676--there's just nothing suggestive at all there, and I don't think it makes sense to group that in with the porn.

The "ratings" page is just from the Danbooru code and hasn't been edited. I'm very sure "exposed" never referred to, uh, labia separation. I've always just rated based on my own intuition of what the useful distinctions are...
