The UK's privacy watchdog has launched an investigation into TikTok, Reddit, and Imgur over concerns about how these platforms are handling children's personal data. This move comes as part of a broader effort to protect young users from potential harm online. The investigation focuses on the ways in which these social media companies collect, store, and share children's information. Experts warn that this can have serious consequences for minors, including exposure to explicit content, targeted advertising, and potential exploitation by predators. The probe highlights the need for greater transparency and accountability among social media giants. Regulators must balance the need to protect children with the need to allow them to use these platforms safely and responsibly.
