Unders who want nude pictures or videos of themselves removed from the internet can now report the images through an online tool. The service - from the Internet Watch Foundation and Childline - aims to help children who have been groomed, or whose partners have posted photos of them online. The IWF will examine the images and try and remove them if they break the law. It says the tool is a "world first" and could help many worried children. The IWF works to remove child abuse material from the internet. The charity says there are a number of reasons a young person might send nude images or videos without knowing they will be posted online, including grooming and coercion.
