It’s the ending of an age. Before this month, Tumblr declared that it would delete all adult content from the stage on December 17. That afternoon, friends, is today.

The blogging platform was furiously flagging posts as explicit because announcing the ban on December 3. Beginning today, all those flagged posts will be concealed from view. The website has been relying on computers to flag the content.

“Computers are better than humans at scaling process–and we need them for this –but they’re less good at making nuanced, contextual conclusions,” Tumblr notes. “This is an evolving process for every one of us, and we’re committed to getting this correct. That is why we will always notify you whether your content has been flagged as mature so you have the chance to examine it and take any further action that may be required.”

The fairly aggressive flagging procedure has led to some hilarious mix ups. As soon as it’s instituted a review procedure for website owners, pages which were autoflagged will continued to be blocked by means of a filter.

Tumblr’s choice to blog articles was spurred on when Apple removed it in the App Store over child pornography issues. The service chosen to have a kind of scorched earth approach to the problem of explicit content, a decision which has concerned artists and gender workers alike. Many have also theorized that the conclusion of pornography may also spell the end of Tumblr (that, for the record, is owned by precisely the exact same company that owns TechCrunch).

In spite of that issue, however, Tumblr’s bid appears to have worked, with the service having since returned to the App Store.
