Meta has announced new safety features for teenagers on Instagram, Facebook, and Messenger, including requiring parental permission for livestreaming and turning off nudity blurring. The updates aim to enhance protections for users under 16 and address concerns regarding teen safety on social media platforms. Teens account safeguards debuted on Instagram last September, and the latest changes will roll out across the U.S., U.K., Canada, and Australia. Despite facing criticism over their effectiveness, Meta reports that 54 million teen accounts have been set up since the initiative began.
