Facebook Inc. unveiled tools to help people when their intimate images are shared without their permission on its social networking site, Messenger and Instagram.

While encouraging users to report such content, commonly referred to as "revenge porn," the company said in an April 5 official blog post that it will also use photo-matching technologies to remove images and block accounts.

Facebook will also use specially trained representatives from its Community Operations team to review and remove images if they are found to have violated the company's policies. Users, however, will have the ability to appeal if they believe the image was removed by mistake.
