Andrew Charlesworth was invited by Susie Hargreaves, Chief Executive of the Internet Watch Foundation to join their bi-annual Hotline audit team as a human rights advisor with internet expertise.

The Internet watch Foundation is the UK Hotline for reporting criminal online content, including child sexual abuse content hosted anywhere in the world, criminally obscene adult content hosted in the UK, and non-photographic child sexual abuse images hosted in the UK. The IWF works with the internet industry, police and international partners to get such material removed. Individuals who come across material of this type online can report it anonymously.

The Hotline audit team's terms of reference are:

- quality checking of active child sexual abuse URLs for consistency of decision-making;

- sampling of previous CSAC screen captures for consistency of decision-making, and

- review of administration in discharging content assessment complaints.

The team was led by IWF's independent inspector, Sir Mark Hedley, a former High Court Judge. The other members of the team were: Claire Lilley, Head of Online Safety, NSPCC; Annabel Poate-Joyner, Clinical Psychologist; D/Inspector Alice Scott, Child Protection Abuse Investigation working group, Norfolk Constabulary.

The team carried out their inspection on 26-27 March 2015 at the Internet Watch Foundation's offices in Cambridge. Their audit report will be published shortly by the IWF.
