The Verge reports:
Tumblr says that child pornography was the reason for its app’s sudden disappearance from the iOS App Store. The app has been missing from the store since November 16th, but until now the reason for its absence was unclear — initially Tumblr simply said it was “working to resolve the issue with the iOS app.”
However, after Download.com approached Tumblr with sources claiming that the reason was related to the discovery of child pornography on the service, the Yahoo-owned social media network issued a new statement confirming the matter.
From Tumblr’s latest statement:
We’re committed to helping build a safe online environment for all users, and we have a zero tolerance policy when it comes to media featuring child sexual exploitation and abuse. As this is an industry-wide problem, we work collaboratively with our industry peers and partners like NCMEC to actively monitor content uploaded to the platform.
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. Content safeguards are a challenging aspect of operating scaled platforms. We’re continuously assessing further steps we can take to improve and there is no higher priority for our team.
Tumblr is owned by a subsidiary of Verizon that also owns AOL, MapQuest, Yahoo, and the Huffington Post.
