Could an iPhone app help address teen bullying? Could a
website connect abused children to help? MTV and its A Thin Line campaign think so.

Among other things, the campaign asks youth to share
their experiences via the app or
on the site, and then other users vote as to whether anyone went "over the
line." The site also directs users to resources such as the National Teen
Dating Abuse Hotline or the police.

On the site, anonymous users share stories on a wide
variety of topics: a hijacked Facebook account used to send insulting messages,
a large cross posted on a Christian student's locker and labeled "Jesus Freak,"
prescription drug abuse, sexting.
