Looking at the fantastic success of services like Twitter and Instagram, it’s clear that we’re enjoying the megaphone.So where does this little app called Rando get off limiting our photo sharing to one single person? to work–that you might think the app is some sort of early April Fool’s prank.

This discreetness has made the app extremely popular for the exchange of racy photos.

But Snapchat also has a surprisingly obvious flaw: users can take a screenshot of the pictures that were sent to them.

And now, recipients of pornographic images are secretly uploading them to "Snapchat Leaked."Anyone can submit a saved picture to the site, which has categories such as "women," "men," "sexy" and "stupid."Its Facebook page has amassed over 500,000 likes in under 20 hours, but has since been shut down.

The site was meant to mimic the wave of "revenge porn" websites that allow bitter ex-lovers to post humiliating photos and videos of their former partners.

But once you play with it a bit, you realize that it’s not an entirely ludicrous idea. On a very basic level, there’s something exciting about the way the app strips away everything but the photos themselves.

It’s an experience that “offers freedom for users on a number of levels,” says Matt Miller, co-founder of ustwo, the digital design studio that created the app.
