TikTok Safety Test Left Millions Exposed

In early 2022, TikTok implemented an algorithmic safety update for only 90 percent of its United States users. The remaining 10 percent, an estimated 15 million individuals, were excluded as part of an experiment to measure the impact of safety changes on user engagement metrics. This exclusion left millions without a crucial safeguard designed to break up repetitive and potentially harmful content.

One tragic outcome was linked to 16-year-old Chase Nasca, whose account was found to be excessively recommended videos about suicide and depression. His family's wrongful death lawsuit is ongoing. TikTok's internal review, prompted by a media inquiry over a year after his death, confirmed his account was trapped in a filter bubble. The review recommended significantly shrinking the experimental control group.

TikTok's CEO testified before Congress about the platform's commitment to teen safety, stating it was a core priority. The company acknowledged using A/B testing for safety evaluations but did not publicly identify specific cases of harm. The internal findings highlight a complex balance TikTok navigated between user well-being and engagement data, a practice now under increased scrutiny from regulators and courts.
