Instagram doesn't allow the female nipple to be shown on uploads. I think that is stupid. What is your opinion on it?
It's their site, their rules. Personally, I would allow exceptions on artistic, historical, or medical grounds. Then again, I've never been on instagram and I have no idea how things are done there.
