Revenge porn hits 'one in five' Australians

The national survey of more than 4,200 people found that men and women were equally likely to be targeted.

But men were more likely to be perpetrators, while women held more safety fears, said Australia's first comprehensive research on the subject.

The findings showed that the abuse was more widespread than previously thought, researchers said.

A fifth of respondents had a sexual or nude image taken without their consent, according to the RMIT University and Monash University study.

Facebook launches tools to combat revenge porn

The term refers to non-consensual pornography that's distributed online to shame, exploit or extort its victims.

And on Wednesday, the company said it would apply photo-matching to ensure intimate, nonconsensual images that are reported once aren't able to be uploaded again through Facebook's properties, including Messenger and Instagram.
