ISPs providing broadband access to 5% of the UKs internet users have failed to block access to websites containing illegal images of child abuse. This is despite the British government asking all ISPs to implement a blocking list supplied by the Internet Watch Foundation (IWF) by the end of 2007. Children’s charities such as the NSPCC believe that, by not blocking access to the child abuse websites, ISPs are helping paedophiles trade in illegal images, which ultimately encourages more sexual abuse of minors.”]
