Tumblr has had a major problem with pornography, and even child pornography lately... which actually led to the app being removed off the App store.
To combat this, the app has removed/banned ALL visual adult content from its site.
The platform's new community guidelines are very specific. “Adult 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,” the company published in a blog post.
Images of nipples related to breastfeeding, birth or images from after birth, or “health-related situations” will be allowed, as will erotica that is written, nudity related to newsworthy events, and “nudity found in art.”
On November 16, Yahoo (who owns the company) confirmed that child pornography was th ereason they were removed from the App store.
“Every image uploaded to Tumblr is scanned against an industry database of known child sexual abuse material, and images that are detected never reach the platform. A routine audit discovered content on our platform that had not yet been included in the industry database. We immediately removed this content,” Tumblr wrote in a blog post, adding, “We’re continuously assessing further steps we can take to improve and there is no higher priority for our team.”
However, a spokesperson has confirmed that the removal from the App store is not the reason why they're getting rid of all adult content.
