After I wrote an article about misogyny found on Facebook, people began to send me links to content that they had tried and failed to have removed by the site. Among these was a seven-minute video depicting a gang-rape of a girl by the side of the road. I began looking more deeply into the subject. I came across humor" pages with names like "Raping Your Girlfriend." There were easily accessed pictures and videos of girls and women frightened, humiliated, bruised, beaten, raped, [and] bathed in blood. In one instance, Facebook declined to remove an image of a woman, mouth covered in tape, in which the caption read, "Don't tap her and rap her. Tape her and rape her." The photo went viral. Facebook's response ... "the photo ... did not violate our community standards." I joined [others] to launch a global campaign to confront institutionalized sexism in media. We wrote an open letter to Facebook, co-signed by more than 100 organizations, asking the company ... to train people to recognize violence against women as hateful. We encouraged users of Facebook to send messages to its advertisers encouraging them to boycott the social media network. Over seven days, men and women around the world sent more than 60,000 tweets ... and 5,000 e-mails to targeted advertisers, 16 of whom withdrew their advertising. Facebook responded, noting that its "systems to identify and remove hate speech have failed to work as effectively" as they would like. We are in the midst of a shifting cultural tide in which gender based violence -- historically kept private -- is better understood as a pandemic problem. Facebook's action represents an open acknowledgment that violence against women is a serious issue [that] deserves serious attention.
