Australia approved on Thursday a social media ban for children aged under 16 in one of the toughest worldwide regulations of such sites. Services must stop minors logging in or face fines of up to $32 million.. The ban has support of 77 percent of the country according to polls. "Putting an age limit and giving the control back to the parents, I think it's a starting point," said Ali Halkic, whose 17-year-old son Allem took his life in 2009 following social media bullying.
