The app is used as a source of entertainment. It's fine when sending funny pictures to friends- actual funny pictures, or sending pictures of something interesting that you'd like to share. However, as kids get older, SOMETIMES-NOT ALL THE TIME-BUT, SOMETIMES- it is a easier way for teens to engage in, 'sexting'. As i've noticed, a young teenage girl 'really' likes this guy and really wants him to like her. He convinces her to send him naked pictures, claiming he can only see it for a few seconds, and that she would be able to tell if he took a screenshot (which is true- the app will tell you when somebody takes a screenshot of your picture). However, unfortunately, there are other apps that were created that go against notifying someone when their picture was screen shotted. Anybody can be taking screenshots of your pictures thanks to these apps, and the person posting them would never find out. Goes against the entire purpose of the app. Even if high school kids were at a party and posted snaps of them drinking- somebody that wasn't invited could get angry, screenshot the pics, and send them in. Be careful!
