Sulli Deals: The Indian Muslim women 'up for sale' on an app

Last Sunday, dozens of Muslim women in India found they had been put up for sale online.

Hana Khan, a commercial pilot whose name was on the list, told the BBC she was alerted to it when a friend sent her a tweet.

The tweet took her to "Sulli Deals", an app and website that had taken publicly available pictures of women and created profiles, describing the women as "deals of the day".

The app's landing page had a photo of an unknown woman. On the next two pages Ms Khan saw photos of her friends. On the page after that she saw herself.

"I counted 83 names. There could be more," she told the BBC. "They'd taken my photo from Twitter and it had my user name. This app was running for 20 days and we didn't even know about it. It sent chills down my spine."

The app pretended to offer users the chance to buy a "Sulli" - a derogatory slang term used by right-wing Hindu trolls for Muslim women. There was no real auction of any kind - the purpose of the app was just to degrade and humiliate.
