Does TikTok protect underage users? RTVE's Innovation Lab has created four fake accounts for children under 13, the minimum age to register on the app, and has found evidence that TikTok doesn't filter content by age. This is one of the concerns of the European Commission, which has opened a formal investigation to verify that the social network complies with the Digital Services Act. The TikToktives docuseries shows the harmful content to which minors are exposed, discusses the app's highly addictive design, and compares it to its twin sister, Douyin, the version available in China.
