In this chapter from the forthcoming Intersectional Internet: Race, Sex, Class and Culture Online (Noble and Tynes, Eds., 2016), I introduce both the concept of commercial content moderation (CCM) work and workers, as well as the ways in which this unseen work affects how users experience the Internet of social media and user-generated content (UGC). I tie it to issues of race and gender by describing specific cases of viral videos that transgressed norms and by providing examples from my interviews with CCM workers. The interventions of CCM workers on behalf of the platforms for which they labor directly contradict myths of the Internet as a site for free, unmediated expression, and highlight the complexities of how and why racist, homophobic, violent, and sexist content exists, and persists, in a social media landscape that often purports to disallow it.
