Blog site Tumblr announced on Monday that it will ban adult content such as explicit sexual content and nudity on the site beginning on December 17.
The platform is currently using algorithms to automatically flag adult content, and notify users that their content will be hidden after December 17.
The site said the banned content “primarily includes photos, videos, or GIFs that show real-life human genitals or female-presenting nipples, and any content—including photos, videos, GIFs and illustrations—that depicts sex acts.”
Tumblr noted that users can appeal their flagged content.
