Eton College has blocked instant messaging app Snapchat from its wireless network over concerns the service is being used by pupils to send and receive sexually explicit images.
No specific details have been released by David Cameron's former school as to what images or videos were being shared by students, though blocking the app from the school's Wi-Fi is unlikely to stop them. Those wishing to still use Snapchat will still be able to access it via the 3G network.
Head master Tony Little told the Sunday Telegraph: "It (Snapchat) is blocked from the Eton wireless internet system. Boys can still use it via the 3G network but we hope that blocking it on our network will, at least, make them think twice.
"This is part of our continuing effort to educate boys in the sensible use of technology."
Since launching in September 2011, the self-destructing messaging app has become one of the largest photo sharing services in the world. It has attracted the interest of investors and even caught the eye of Facebook, which tried to buy the app in November for a reported $3 billion (£1.9 billion).
Despite this success, Snapchat has been unable to shake off its image as a service used to exchange explicit images. Snapchat founder Evan Spiegel has previously iterated that the app is not just a 'sexting' service.
"With 150 million images a day, it's possible some of them are like that," Spiegel said last April. "11 p.m. is when traffic starts slowing down. Some people are surprised and say 'I thought that's when things would just be getting started!'
"I don't think it's a great tool for sexting. We notify you about screenshots. It's not a great way to send inappropriate content."
