TikTok’s secret algorithm has been blamed for sending young users content that pushes some into a spiral of self-harm, disordered eating and suicide. In this episode of Bloomberg Investigates, we meet a 13-year-old girl recovering from anorexia nervosa and a former TikTok employee who reveals the warnings he gave colleagues about the app's algorithm. And we see what TikTok continues to send a 16-year-old boy who, according to his parents and their attorneys, killed himself because of the disturbing content that kept landing in his "For You" feed.
