The Internet Watch Foundation has started a campaign to let internet users know how to report illegal content online.

The campaign is a response to recent IWF research that revealed 77% of people who find illegal content do not know how to report it.

Illegal content, such as images of child sex abuse, obscene pornography or race hatred, can be reported by clicking a big red button on the IWF home page.

Those who want to report content can report what they have found anonymously or can leave contact details if they want to find out what has been done about the pages they found.
