While many of us are already familiar with the popular photo sharing app that is Snapchat – it seems it’s popularity is now moving to a younger demographic.

13-year-old, Ruby Karp revealed in an account for Mashable that the app is now being used as form of free communication between teens.

She said like the majority us, that she mostly uses the app to share selfies with friends.

Ruby who is from New York, talked about the downsides of Snapchat  as well, which is the nude selfies.

“But it can also be used for other types of photos: the stuff of nightmares for parents. With Snapchat, your nude cannot (typically) be traced back to you, due to the fact that the photo literally lasts 10 seconds, or less. This is pretty appealing to teens and adults looking for a ‘good time.’”

Ruby even shared a screenshot of one incident where she was asked to send a nude selfie. While the 13-year-old said she wasn’t comfortable with sharing intimate shots on the site she was aware of some friends who did.

“There have been incidents with nudes being screenshotted among my friends. And remember Snap Save an app where you can screenshot the picture sent to you, without the person knowing.”

While the photo sharing app can be used a great way of free communication between friends, Ruby also highlighted that it can also be used as a tool for bullying.

“I try not to say anything risky in text messages, and I think bullies have the same method: They’re saving it for Snapchat. I have received hurtful Snapchats, but I have no proof that they ever said anything to me, because the picture went away in 10 seconds.”

While Ruby acknowledged the downsides of using the app, she insists parents have nothing to worry about.

“I think it is up to you how you use the app. And to every overprotective parent out there: As crazy as it may sound, don’t fret too much over the app. I’m sure your kid is just sending some ugly selfie of themselves! But if your kid takes off clothing, goes into the bathroom, shuts the door and you do not hear the shower water coming on: Be very afraid.”
