Summary: In 2012, the Huffington Post did an exposé on eating disorder blogs, mainly on the site Tumblr. It discussed the world of “thinspo” and “thinspiration” blogs, that focused on building a community around losing unhealthy amounts of weight. In response, Tumblr announced that it was banning “self harm” blogs, and classified eating disorder blogs among those no longer allowed.

Three years later, a study by Munmun De Choudhury discussed how there was still eating disorder information on Tumblr, but that it was mainly split into two different categories: those who were supportive of eating disorders such as anorexia (referred to as “proana”) as well as communities built up around recovering from eating disorders. One interesting finding of the report was that the “recovery” groups often used the same keywords and messaging, in an attempt to permeate among the “proana” groups, in order to try to encourage those with eating disorders to seek support, therapy, and help towards recovery.
