Social media giants have hit out at a landmark Australian law* banning them *from signing up under-16s,* describing it as a rush job littered with _"many unanswered questions"._ 🇦🇺📱 The UN children's charity *UNICEF Australia warned the law was no _"silver bullet"_ against online harm* and could push kids into _"covert and unregulated"_ spaces online. The legislation, approved by parliament Thursday, *orders social media firms to take _"reasonable steps"_* to prevent young teens from having accounts. It is *due to come into effect after a year.* The *crackdown on sites like Facebook, Instagram and X* would lead to _"better outcomes and less harm for young Australians"_, Prime Minister Anthony Albanese said. The *legislation offers almost no details on how the rules will be enforced* -- prompting concern among experts that it will be largely symbolic.
