Children's charities have been drawn into an argument with the founders of the Chatnannies website, which recruits volunteers to anonymously monitor children's chatrooms for paedophile activity.
Jim and Eleanor Wightman, who launched the site in March, initially listed the NSPCC and Barnardo's on the site and said the charities would receive 10 per cent of any sponsorship. But the charities have denied any link and demanded their names be removed.
The site also has a section where paedophiles can get confidential help from counsellors. John Carr, internet adviser to NCH, said this was "extremely dangerous".
"No self-respecting counsellor would deal with this without involving the police because it can become a prop for the offending behaviour," he said.
Mrs Wightman said they tried to contact charities before the site launched.
The charities deny this.
