Pinterest is the latest social media to ban pro-anorexia contents from its platform.

This move follows Tumblr's ban on self-harm blogs last month, as Pinterest also received criticism on the messages conveyed by its forums like "thinspiration" and hashtags like #thinspo and #perfect.

Friday evening, the social media announced new guidelines that include a ban of any content which “creates a risk of harm, loss, physical or mental injury, emotional distress, death, disability, disfigurement, or physical or mental illness to yourself, to any other person, or to any animal.”

Caitlin Boyle, a blogger and author of the book "Operation Beautiful" told ABC News, "The thing I have noticed with these thinspiration sites is it really normalizes distorted behavior.”

“It makes the viewer of this content believe their behavior is O.K. and acceptable.”

Her campaign aims at spreading positive and healthier messages.

“When people view social media sites that are positive, it encourages them to think more like that, even when they leave the site,” Boyle said. “It can have a positive effect on their self-esteem.”

The cult-like movement of pro-anorexia and pro-bulimia movements have accelerated since the dawn of the Internet, encouraging people to, basically, eat less.
It is estimated that seven million women and one million men in the U.S. are suffering from eating disorder. 95% of those are between the ages of 12 and 25, according to South Carolina Department of Mental Health. Furthermore, 50% of girls between the ages of 11 and 13 see themselves as overweight, and 80% of 13-year-olds have attempted to lose weight.

Is Pinterest making a wise move? Will it have any measurable influence on how beauty is perceived? Let us know your thoughts.
