They actually flagged it for deletion for that? You can't even see the waist. And believe me, I've watched enough porn to know a girl can very much turn her body in ways you wouldn't believe. Plus, I've seen much worse shit on here that's gotten approved. These admis who approve uploads are very discriminate in what they approve, that it's never consistent. They have no true logic when approving anything, since some things contradict the things that's gotten approved.
Not everything needs to be visible. A human's body is also defined by things you don't see (ike in post #2289230 where the upper torso isn't visible too or only little parts of it :3). And this post here....it looks a bit weird in my eyes, maybe I wouldn't be so strict to call it awful, but the flagger has a point.
