Australia's eSafety Commissioner, Julie Inman Grant, has warned big tech platforms that they must do more to tackle the problems caused by anonymous accounts on their services, ahead of the proposed introduction of new powers that could force individuals to be unmasked and see fines levied.

Anonymous social media accounts used by proponents of the far-right conspiracy theory QAnon were prominently cited by members of the mob that stormed the US Capitol on January 6. The government, meanwhile, has already opened up consultations on new laws to force tech platforms to take abuse, abhorrent material and trolling more seriously.
