We do have a nude section, as pointed out. Most of the photos there are, simply put, snapshots of people without their clothes. The few that I've posted to that section have -NSFW appended to the title, since the site doesn't list the section to which a photo is submitted when it appears in the Upcoming Topics section, I include that as a courtesy to those who may be viewing the site from a work computer.
Obviously, pornography sort of photos are most likely against the rules. A look at
will probably be a good guide for you.
I have tried searching but don't find anything vary specific. What are the rules for posting photos with partial nudity (breasts). Is there a way to flag them as adult only.
I would like to post photos of African tribes but many of the women are bare from the waist up, or partially. Some also involve scarring, etc.
