The UK's privacy watchdog, the Information Commissioner's Office (ICO), has launched investigations into TikTok, Reddit, and Imgur over their handling of child privacy. The ICO is examining how TikTok uses personal information of 13- to 17-year-olds to recommend videos, amid concerns about harmful content. The regulator is also investigating how Reddit and Imgur assess the age of their users in the UK and use children's personal information. The probes are part of a broader effort by UK authorities to hold social media platforms accountable for protecting children's privacy. Last year, the regulator Ofcom launched an investigation into OnlyFans over alleged age-verification failures, which was later dropped. In 2023, the ICO fined TikTok $16 million for providing services to children under 13 without parental consent. The ICO's investigations will determine whether the social media companies have infringed on data protection legislation. The regulator will decide on its next steps after assessing the findings. The move highlights the growing concern about social media platforms' handling of child privacy and the need for stricter regulations to protect young users.
