Tumblr is back. Sort of. The social blogging platform reappeared on Apple’s App Store this week, some three weeks after being pulled over child pornography concerns. Ten days ago, the company adopted a scorched earth response to the issue, announcing a blanket ban on adult material as part of a “better, more positive Tumblr.”

The move appears to have paid off on one front, at least. The iOS version has returned to Apple’s hallowed halls with a version history noting that “this particular update[…]includes changes to Tumblr’s Community Guidelines, which prohibit certain kinds of content from being shown on Tumblr.”
