Are You're a Cyberbully? Try MTV's 'Morality Meter'

Teens wondering whether their online behavior has crossed the line into sexting or cyberbullying will be able to get an answer from a new MTV "morality meter" app. Over the Line? lets young people share stories about what they're up to online and invites users to rate those stories to "define the line between innocent and inappropriate," ABC reports.

Launched today, the app ties into MTV's ongoing campaign to end online abuse, a network exec says. A study released by MTV last year found that half of all young people have been the victims of cyberbullying or other online abuse, and that 30% have sent or received nude photos of other young people online or via cell phone.
