Instagram and Facebook allow photos of male nipples on their sites, but not female. In response, artist Spencer Tunick organized a group of male and female models to protest by posing naked and holding large photos of nipples near the Astor Place subway station in Manhattan.
The photos of nipples being held by Tunick's models were donated shots from a number of high-profile celebrities, including Bravo’s Andy Cohen, Red Hot Chili Peppers drummer Chad Smith and Tunick himself.

Tunick organized the photo shoot in collaboration with the National Coalition Against Censorship, who have pioneered the hashtag #WeTheNipple.
'The nudity ban prevents many artists from sharing their work online. It particularly harms artists whose work focuses on their own bodies, including queer and gender-nonconforming artists, and the bodies of those in their communities,' their website says.
