Facebook will help UK teens fight cyber abuse and bullying by deploying a panic button on its sites. Teens will be encouraged to click it when suspicious that they’re being targeted for abuse.
The button will actually connect the teens with resources hosted by the Child Exploitation and Online Protection Centre (CEOP), an organization run in part by the UK government. Teens will be given advice and resources on dealing with potential threats on the Internet(), and they may also report users who they believe are acting inappropriately toward them.
The tool will be advertised on the home pages of teenage Facebook() users.
