What happened

YouTube's recommendation algorithm has allegedly been directing teen users to harmful content promoting eating disorders and self-harm, according to a study by the Center for Countering Digital Hate. Almost 70% of the recommended videos in searches related to dieting or weight loss reportedly contained content likely to exacerbate body image anxieties.
