Parse recently partnered with CrowdFlower, "the world's largest crowdsourced workforce," in order to create a new module for RTFM - Real Time Foto Moderation. From the Parse Blog post:
Many applications include photo sharing amongst friends, family, and the world. Moderating these images can take a lot of time and resources. By crowdsourcing this tedious task, developers that create applications that include photo-sharing, like the Parse-powered TOMS app, don’t have to create a complex workflow to manage moderation. Parse developers now have the power of millions of eyes moderating their content with just a few lines of code.
