Hannah Smith suicide: 'Ask.fm hits 70 million users': tweet of website Father Dave Smith says bosses at social network are 'dancing on her grave' Ask.fm tweeted yesterday it had 70m users - 10m more than six weeks ago Hannah killed herself 10 days ago after trolls said 'go die' and 'drink bleach' Executives say 98% 'sent from a computer with same IP address as her's' Gloating: Ask.fm has proudly revealed a surge in numbers since the suicide of Hannah Smith, who blamed bullies on the site The shameless website blamed for allowing trolls to drive teenager Hannah Smith to suicide has bragged about how it has had a record number of users. The 14-year-old's father David Smith today called Ask.fm 'heartless b*******' after the Latvian-based social network exclaimed millions more had signed up since his daughter's death ten days ago. Mr Smith said it was like they were 'dancing on Hannah's grave'. The site, which David Cameron called 'vile' and demanded people boycott, tweeted yesterday: 'Ask.hits 70million registered users'. Hannah hanged herself on Friday, August 2, after anonymous bullies on the site told her to 'go die', 'drink bleach' and 'get cancer'. Her father told the Daily Mirror: "It just proves what a heartless bunch of b******* the people that run the site are. 'It should be shut down, but instead they're boasting about the numbers of hits and members they've had - and all the while, the Government is doing nothing.' Ask.fm claimed yesterday it has 70million users, but six weeks ago it tweeted it had 60million users. Based on those figures it makes £6million a year on advertising, although last week some of Britain's biggest businesses started pulling out because of its image as a place for anonymous bullying. It came just 48 hours after the website's bosses claimed the teenager sent most of the vile abuse to herself. It was reported the social networking site insists that she set up most of the anonymous identities used to bombard her own page. Boast: The Ask.fm Twitter account rarely tweets but yesterday it revealed a huge rise in users - 10m more in six weeks Upsetting: Hannah Smith and her father Dave when she was a baby and and as a teenager, and he said today Ask.fm were 'dancing on her grave'
