The owners of a social networking website linked to the suicide of a Leicestershire teenager have announced safety improvements following her death.
It is claimed 14-year-old Hannah Smith, from Lutterworth, took her own life after receiving anonymous abuse through the site.
The founders of Ask.fm are now promising to introduce additional features to make the site safer.
Sally Lockwood reports.
David Smith, whose 14-year-old daughter Hannah was found dead in her bedroom earlier this month, described Ask.fm's new measures as "a good thing".
But he said that in making changes, the site had "admitted that their website was dangerous for teenagers."
"It's now time for the Government to step up and start regulating these websites so that a 45-year-old lorry driver doesn't have to do it, because I haven't got time to do it any more," he added.
"It's not just Ask.fm, it's the whole internet. The Government actually do need step up and start regulating this internet to make the internet a safer place."
Dave Smith, father of Hannah Smith who killed herself after being bullied online, is 'pleased' with the changes announced by Ask.fm
Alex Holmes, an anti-bullying programme manager, says Ask.fm's announcements are positive steps towards internet safety.
In its statement, Ask.fm said changes include reviewing all reports made using the report button within 24 hours and hiring more staff to act as moderators, including a Safety Officer to take overall responsibility for moderation at the site.
To encourage people to join the site, unregistered users will not be able to access the same amount of features on the site as registered users.
Efforts to encourage people to register will mean the site will be able to record the email and IP addresses of users and deal better with reports.
The website, Ask.fm, used by cyberbullying victim Hannah Smith from Lutterworth, is due to publish the action it will take to combat the problem.
It postponed its announcement from last Friday to avoid clashing with Hannah's funeral.
The 14-year-old took her own life after receiving malicious anonymous online messages. Her father Dave Smith has called on the Prime Minister to do more to tackle the problem
Ask.fm co-founder Klavs Sinka has suggested comments in the British media attributed to the social networking site about cyberbullying victim Hannah Smith were "distorted".
In an exclusive interview with ITV News, Mr Sinka claimed the hype surrounding the story was the work of the worst of the British press.
Mr Sinka said, "This is also why we have been avoiding making any comments, because we see that we can say anything but it will be twisted and turned back on us regardless of what we meant."
Ask.fm co-founder Klavs Sinka told ITV News in an exclusive interview that other social networking sites "could learn" from Ask.fm when it comes to its moderation policies.
Mr Sinka said, "I am not afraid to say that Ask.fm is one of the best controlled, best moderated and regulated projects".
"One could learn from us," he added.
The co-founder of social networking site Ask.fm told ITV News he believes David Cameron "did not have all the information about the case" when he urged parents to boycott "vile sites" following the death of cyberbullying victim Hannah Smith.
Klavs Sinka said he believed the Prime Minister "hadn't really researched" the case before he made his comments.
He continued, "He was probably caught on the street in an interview similar to this and made a comment without having the full information about this case."
