Internet Watch Foundation

The Internet Watch Foundation (IWF) is a registered charity based in Cambridge, England. It states that its remit is "to minimise the availability of online sexual abuse content, specifically child sexual abuse images and videos hosted anywhere in the world and non-photographic child sexual abuse images hosted in the UK." Content inciting racial hatred was removed from the IWF's remit after a police website was set up for the purpose in April 2011.
