If each mod's or admin's opinions differ, then they can't give mutually consistent views on allowable nudity if they are asked independently, behind each others' backs. That's a sneaky way of doing it, since it pits one against another. So it might make everyone happier if the mods and/or admins gave their consensus view on any image, and didn't leave it to the vagaries of any one person. Then they can issue a majority opinion when somebody asks if an image is o.k., assuming they can find enough staff personnel who don't mind spending a few minutes or hours per day judging nudity. The downside to this is that it can be considered sexual harrassment if somebody is asked to view porno or nudity against his or her will. So they would need a committee of 5, for example, all of whom state beforehand that they won't be offended by viewing images of nude women or men.
