Snapchat users got a surprise in their inboxes Tuesday morning, but not (for most) a pleasant one. It was the service's first spam: A naked lady accompanied by a Skype name.
It wouldn't be the first naked pic to be sent on the service, which was lauded (and put down) early on as a safe way to "sext." Snapchat messages and pictures disappear after just 10 seconds, meaning titillating shots can be sent without much fear that they'll be passed on. (You can always take a screenshot, but Snapchat lets the sender know you did.)
Despite (and perhaps because of) the early hysteria about the service, it has grown immensely popular: 150 million images a day are being sent on Snapchat. And they can't all be naughty.
But as on any successful new platform, be it Facebook, SMS, or even email when it was new, the dreaded spam was sure to appear. And appear it did Tuesday; The naked pics and Skype addresses were probably to entice users into joining porn sites. Users took to Twitter to express their ire.
The spammy images were only sent to those who had the app set up to accept messages from anyone, not just friends. Snapchat apologized in a blog post for the incident, and advised everyone to use the more restrictive "friends only" mode.
