Susan Grantham of Australia's Griffith University warns that new rules to ban under 16s from social media could 'push young people to places that aren't regulated'. The landmark legislation was passed in the Australian Senate on Thursday night, and orders social media firms to take "reasonable steps" to prevent young teens from having accounts. The firms -- who face fines of up to Aus$50 million (US$32.5 million) for failing to comply -- have described the laws as "vague", "problematic" and "rushed". SOUNDBITES
