CNET portal, through independent sources, found out that the application was removed due to the presence of child pornography that passed through site filters. After providing this information to Tumblr, a company representative posted astatement confirming the guesswork.
We are committed to helping create a secure online environment for all users, and we have a zero-tolerance policy when it comes to content related to sexual exploitation and child abuse.
Since this is a problem for the entire industry, we are working with our industry colleagues and partners, such as the National Center for Missing and Exploited Children (NCMEC), to actively monitor content loaded on the platform.
Each image uploaded to Tumblr is checked against a database of known materials of child sexual abuse and does not fall on the platform in the event of a match. Regular check found content on our platform that is not yet included in this database. We immediately removed these materials.
Content protection is a complex aspect of scalable platforms. We constantly evaluate further steps that we can take to improve [the situation] and for our team there are no [tasks] of higher priority.
Initially, neither Tumblr nor Apple publicly disclosed the nature of the “problem”. The disappearance of the application occurred on November 16, but then Tumblr representatives called it “malfunctions.”
