Tumblr’s new policy is also the latest installment in a ridiculous war against women’s nipples. Women’s top halves have long been sexualized and policed in a way that men’s aren’t, both online and offline. Janet Jackson, let us never forget, was disgraced, and saw her career bottom out, when Justin Timberlake tore her top at the 2004 Superbowl half-time show, and revealed a bit of breast. More recently tennis player Alizé Cornet was penalized for briefly removing her shirt at the US open. While male tennis players are allowed to go topless, seeing a woman’s sports bra is apparently appalling.

The big social networks, which don’t seem very keen to do anything about the conspiracy theories and rightwing hate groups hijacking their platforms, have been very active in battling breasts. Instagram’s censorship of female breasts, for example, led to a campaign called #freethenipple. Facebook also exerts considerable energy in regulating women’s chests. Its community guidelines state that nipples are generally no bueno, unless they belong to women who are actively engaged in breastfeeding, or photos of post-mastectomy scarring.

Social networks are always going on about how they’re not evil data-mongers; they simply want to make the world a better place. Well, here’s some quick and easy advice for Tumblr et al: why not spend a little less time worrying about nipples, and a lot more time worrying about Nazis?
