Hannah Smith Suicide: Father Attacks Ask.fm A 14-year-old girl killed herself after being abused by 'trolls' on a social networking site, her father has said. Hannah Smith died on Friday in Lutterworth, Leicestershire after being 'cyber-bullied' on the question-and-answer website ask.fm. Her father, Dave Smith, has called on authorities to close down the site after he saw some of the abuse that he believes drove his daughter to take her own life. The site, popular with teenagers, allows users to anonymously post comments or questions on another person's profile. In the weeks leading up to her death Hannah received messages criticising her appearance and telling her to kill herself. Then, the day before she took her own life, she posted a picture online which read: "You think you want to die, but in reality you just want to be saved." Writing on Facebook, her father said: "On Friday morning my daughter was found hanged ... (I saw) her ask.fm account and someone had been telling her to die. I have just seen the abuse my daughter got from people on ask.fm and the fact that these people can be anonymous is wrong. Hannah had got messages telling her to kill herself. Pic: RIP Hannah Smith The person that created this website should be done for manslaughter. Any parents that have children please don't let them go on this site. Although people wanting to use ask.fm have to register an email address, name and date of birth, those posting messages can choose to do so without revealing their identity. An inquest into Hannah's death opens on Tuesday and Leicestershire Police said a computer and mobile phone had been taken as part of that investigation. The teenager's death is not the first time that ask.fm, which is based in Latvia, has been criticised. Ciara Pugsley, 15, and Erin Gallagher, 13, from Ireland, took their own lives in separate incidents last year after being bullied on the site. A petition urging action against ask.fm and similar sites has now been set up on the Government's e-petition website. It claims activity on the site "has led to bullying, mental health problems and suicides as well as grooming." "[Users] are able to join from the age of 13 and can post anonymously," says the petition. There is no option to block other users and only a basic 'report' button. Hannah's death comes after high-profile criticism of Twitter for not doing enough to deal with abuse, threats and 'trolling' on the site. Sky News has contacted ask.fm for comment and is waiting for a response. :: Anyone feeling emotionally distressed or suicidal can call Samaritans for help on 08457 90 90 90 or email jo@samaritans.org. :: BeatBullying.org is also available for advice and support.
