Indonesia has become the first country in South-East Asia to ban children under the age of 16 from using social media, as Governments around the world move to protect young people from online harm. The measure came into force on Saturday, with children set to be blocked from creating accounts on platforms including YouTube, TikTok, Facebook, Instagram, Threads, X, Bigo Live and Roblox, all of which the Indonesian Government has classified as high risk.
