A bald, single dad with a beard must be careful about posting a selfie on Tumblr. As of Dec. 21, there are at least four different ways Tumblr might block access to his blog post, in order to comply with the stringent safety standards Apple maintains for all apps on its App Store.

Tumblr now limits users’ ability to search for posts tagged “bald,” “single dad,” “beard,” and “selfie,” among hundreds of other keywords, for fear of running afoul of Apple’s safety standards. In a Dec. 21 update, Tumblr developers said they were expanding “the definition of what sensitive content is as well as the way you access it in order to comply with [Apple’s] guidelines.” They noted that some search queries may turn up fewer results than usual, and others “might not produce any results at all.”
