San Francisco: A former content moderator at Facebook has sued the company alleging that moderators who face mental trauma after reviewing distressing images on the platform are not being properly protected by the social networking giant. “Ex-contractor Selena Scola has sued Facebook for allegedly ‘ignoring its duty’ to protect moderators who deal with mental trauma after seeing disturbing imagery. “Rather than create a safe environment, it’s producing a ‘revolving door of contractors’ who are permanently scarred by what they’ve seen, Scola’s lawyer Korey Nelson said,” Engadget reported on Tuesday. According to the lawsuit, moderators at the social media giant under contract are “bombarded” with thousands of videos, images and livestreamed broadcasts of child sexual abuse, rape, torture, bestiality, beheadings, suicide and murder.
