Anonymous Indian hackers claim to have posted the personal details of 1.7 million Snapchat users on the deep web, in response to the app's CEO allegedly calling India a "poor country".

Snapchat denies that any hack has taken place, and also denies that CEO Evan Spiegel ever said the app was "only for rich people" and not for "poor countries like India and Spain", as Variety magazine reported.

But that hasn't stopped angry Indian consumers dragging the app's rating from five stars down to one on the Apple store, launching #UninstallSnapchat and #BoycottSnapchat campaigns on Twitter, and allegedly compromising nearly 2 million accounts.

A spokesperson for the $25 billion (£19 billion) app said in a statement: "This is ridiculous. Obviously, Snapchat is for everyone. It's available worldwide to download for free.

"Those words were written by a disgruntled former employee. We are grateful for our Snapchat community in India and around the world."

The allegations were made in a lawsuit filed by Anthony Pompliano, a former Facebook employee who jumped ship to the mobile-only platform only to leave on acrimonious terms.

He claims to have uncovered "wide-spread, systemic failure in Snapchat’s internal controls over its user data," meaning the company inflated figures such as its number of active users.

In arguments entirely denied by Snapchat, he says his findings were dismissed by Mr Spiegel, then aged 25, and that he was fired just two weeks into his job.

While the case is yet to be settled by a Los Angeles Court, the allegations have been taken extremely seriously by the estimated 4 million Snapchat users in India.

Snapchat leak affects tens of thousands

An estimated 300 million people use the app at least once per month, while 2.5 billion snaps are sent every single day – or 30,000 per second.

75 per cent of those users who send a Snap every day are in North America or Europe.
