YouTube, similarly, bans “ explicit content meant to be sexually gratifying”, and Tumblr made headlines when its pornography-supporting community saw their content removed (with one-fifth of users leaving the site as a result.) Facebook, and its subsidiary Instagram, does not allow nudity that shows genitals or female nipples – a decision that has been repeatedly criticised for sexism. Twitter is also distinct from other prominent platforms in that it does allow pornographic content, albeit not in the profile photo or header image.
