Apple axed Tumblr from App Store because of failed child pornography filters
Tumblr's sudden disappearance from the iOS App Store on Friday -- still unresolved -- was because material slipped through the blogging network's child pornography filters, according to the company.

"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," it said in a support update. "A routine audit discovered content on our platform that had not yet been included in the industry database. We immediately removed this content."
Work continues on returning Tumblr to the App Store, the company said, without saying what changes are being made or an expected timeframe. For reasons unknown the app remains available on Google Play for Android devices.
Apple has adopted a zero-tolerance policy, choosing to pull any app with accessible child pornography even when it may be hard to find and developers are continuously trying to root it out. Another example is in February, when the popular messaging app Telegram was pulled. Apple worked with Telegram to get the illegal content taken down, ban the offending users, and institute controls.
That process took about a day however, raising questions about the obstacles Tumblr is encountering.

As for those browser...the user has to SEARCH or enter in address of porn.
Tumblr is different.
I figured the moronic comments would come. Safari is a web browser. It doesn’t host any content. Using your logic we should ban the iPhone because someone could use it to take pictures of child porn. Stupid.
Nah, mate. Any developer creating a platform that can share photos is well aware of the risks. Tumblr is well aware, and they put all images through a filter.
The risk to Apple of allowing your unfiltered app to serve up child porn is greater as they would be seen to not be interested (much like Google in this case).
Apple did the right thing here. Tumblr did the right thing here.
Also - by the same metric apps like Periscope are still up because they have a 17+ rating?
Scare developers? Don’t worry about that, the best apps and the best games ALWAYS come to iOS first or exclusively. iOS is the PREFERRED OS for developers. You guys don’t need to worry about us. Thanks though.
You Android fanboys need to worry about your Play Store, which consists of malware-infested fake apps and 2nd rate apps.
Yes, but did you think the comments would be THAT moronic?
Some people here are on the verge of saying 'free speech is more important than preventing the spread of kiddie porn'.
Maybe you should go back to Android side and criticize Google for not doing the same because CLEARLY, Tumblr developer is at (and admit to) fault!
But, go on, and fight against the “man” while we laugh at your sorry arse.
For many reasons, I hope Apple doesn't have to do this again.
