LONDON (AP) — The European Union opened fresh investigations Thursday into Facebook and Instagram over suspicions that they're failing to protect children online, in violation of the bloc's strict digital regulations for social media platforms. It's the latest round of scrutiny for parent company Meta Platforms under the 27-nation EU's Digital Services Act, a sweeping set of regulations that took effect last year with the goal of cleaning up online platforms and protecting internet users. The European Commission, the bloc's executive arm, said it's concerned that the algorithmic systems used by Facebook and Instagram to recommend content like videos and posts could “exploit the weaknesses and inexperience” of children and stimulate “addictive behaviour."
