An internal TikTok document reveals the platform deliberately excluded roughly one in ten American users from a content-filtering system designed to limit exposure to self-harm material, creating a control group to measure engagement metrics. The company knowingly allowed vulnerable users—including a teenager who subsequently died by suicide—to be fed algorithmically amplified harmful content in service of growth testing, transforming a safety feature into a variable in a business optimization experiment. The exclusions were documented product strategy, not a bug or oversight, raising questions about whether TikTok's legal compliance efforts around teen safety have ever been genuine.
