Teen Suicide: Site Refuses To Answer Questions
Staff at ask.fm - the Latvian-based website where a teenager was bullied before she took her own life - have refused to tell Sky News about its system for reporting abuse.
It comes as the father of victim Hannah Smith called for the website's owners to be charged with manslaughter.
And businesses including Vodafone, Phones 4u, Specsavers, Laura Ashley, DialAFlight and Universelook as well as charities Mind and Save The Children have pulled their advertising on ask.fm amid "deep concerns over cyber bullying".
The 14-year-old girl from Lutterworth, Leicestershire, took her own life on Friday after being abused on the social networking site.
Dave Smith has accused the website owners of not caring that "teenagers are dying and killing themselves".
Speaking to the Daily Mirror in his first on-camera interview since Hannah's death, Mr Smith said: "The people that run it should get done for manslaughter or murder because you try contacting them and they don't care.
"These websites should be got rid of, if nothing else they need to be regulated and they need to stop people from doing this."
"If David Cameron was sitting here now I would want to know why he hasn't done something about this six, 12 - two years ago. Modern technology has gone on but the laws have stuck the same."
Ask.fm allows users to post anonymous questions and messages but has been criticised for not doing enough after several other teenagers took their lives - apparently after receiving abuse on the site.
Hannah committed suicide after repeated messages encouraging her to kill herself and criticising her appearance.
Sky's Ian Woods approached an employee in Riga, Latvia and asked to see the system for how the firm moderates its messages and how it reports and tackles abuse.
But the worker said the correspondent should speak to an official from the company.
Mr Smith and Hannah's stepmother Deborah said people needed to think more about the effect of their online posts as it emerged their elder daughter Jo has also been the target of abuse on the site.
"How could you?", Mrs Smith said. "People need to stop and think. You can't just sit behind a keyboard and type something and think that doesn't matter. There's a complete lack of emotional intelligence."
Mr Smith added: "There's something not right with the world today that people can tell someone to die so many times that they actually do it."
The Prime Minister David Cameron has promised the Government would look at any action it can take to stop future tragedies like Hannah's death, which he called "an absolutely appalling case".
He also said: "The people that operate these websites have to step up to the plate and show some responsibility."
Ask.fm has called her death a "true tragedy" and said it is cooperating with Leicestershire Police's investigation.
In a statement the site said it actively "encourages users and their parents to report any incidences of bullying", either by using the in-site reporting button, or via the website's contact page.
"All reports are read by our team of moderators to ensure that genuine concerns are heard and acted upon immediately - and we always remove content reported to us that violates our Terms of Service," the statement added.
