Hannah Smith death: 'Bullying' website launches review
The website at the centre of a row about cyberbullying says it has ordered a "full and independent audit" of the site and its safety features.
Latvian-based ask.fm said it had engaged law firm Mishcon de Reya to carry out the review.
A statement from the site's owners said they were "committed to providing a safe environment" for its users.
Hannah Smith, from Leicestershire, was found hanged last week. Her father said she had had abusive messages on ask.fm.
