Tumblr has no qualms whatsoever about shutting down threads that could promote disordered eating and self harm. This is understandable, even if they can be a bit heavy-handed at times in seeking to keep such negative influences out of the community as a whole. Unfortunately, it is clear that Tumblr only currently focuses on one side of that issue; undereating disorders. Obesity is a very big problem not only in the United States, but around the world. It has real, negative consequences on one's health and lifespan, and can send one to an early grave. It is the the most common means of self-harm in the US today, and blogs promoting this form of self-harm should be treated with the same sort of zero-tolerance policy as those promoting damaging under-eating.
