On Dec. 17, Tumblr will remove all adult content from its platform, erasing the work of thousands of fan artists, shippers, pornographers and just about anyone with “female-presenting nipples.”

The new terms and community guidelines ban users from uploading “real-life human genitals” and “any content, including images, videos, GIFs, or illustrations, that depicts sex acts.”
