When David, a content moderator, heard that his company, Sama, would be ending its contract with Meta, he became one of 260 employees who had to start the search for another job. David, who asked that his real name not be used for fear of retaliation, worked for Sama for several years, making sure images of violence, child abuse, and sexual exploitation stayed off Facebook and Instagram. He made about 60,000 Kenyan shillings ($483) a month.
