Hannah Smith, 14, was discovered dead in her bedroom by Jo, 16, last Friday after she had been targeted by bullies on Ask.fm. Jo said last night that trolls have started abusing her as well following the death of her sister. Taunts: Jo, 16, pictured with her father David Smith, revealed that she has been targeted by internet trolls in the wake of her sister's death They have even targeted a Facebook tribute page set-up in memory of Hannah from Lutterworth, Leicestershire. The page has attracted more than 80,000 'likes' as people pay their respects - although a cruel minority have posted abuse. Jo, 16, said she had been sent heart-breaking messages to her Facebook inbox while others have posted sickening messages directly on her page. 'I've just lost my sister and now I've got to deal with getting abuse myself,' she told the Daily Mirror. 'These trolls don't care what happened to Hannah or what we're going through, they just live in their sad little worlds. 'It's really upsetting. I'm struggling to cope with what's happened and don't need these trolls hounding me.' Jo described her sister as 'a beautiful person and so full of life and love'. Web abuse: Hannah Smith, 14, was found hanged in her bedroom in Lutterworth, Leicestershire, after being taunted on Ask.fm Victim: Hannah Smith, 14, was discovered dead the day after posting a heart-breaking message online Last night a family member said they wanted to take the Facebook tribute page down in the wake of the abuse they had received. The mother of two Irish teenagers who took their own lives has said the Ask.fm tragedy has forced her to relive the deaths of her two girls. Lorraine Gallagher's daughter Erin, 13, (left) was also bullied on the website in the weeks before her death last September. Just a few weeks later her older sister Shannon, 15, (right) took her life as well. Ms Gallagher said she first learned of Hannah's death when she saw pictures of her two daughters on television yesterday. I was sure exactly what was going on and I just saw pictures of Erin and Shannon on the television screen. I then realised that another young girl had taken her own life and it was as a direct result of being bullied through Ask.fm. I couldn't breathe for a while as I tried to take it all in.' Lorraine said she was again begging the Irish Government and Governments around the world to ban the website. She added: 'How many deaths will it take before the authorities realise that Ask.fm is harming our teenagers? If people were telling children where to get drugs or alcohol, we would be quick enough to close it down. 'But it doesn't seem to matter that children are allowed to be bullied online by anonymous people. It has to stop,' she said. They wrote: 'Unfortunately I am going to deactivate this page, there is just too many people writing disrespectful comments and cant keep them too them self, this was a page for respect and something to remember Hannah by.' Website Ask.fm has described Hannah's death as a 'true tragedy' and promised to work with police investigating the incident. The question-and-answer site allows users to send messages to one another without their identity being disclosed. Although users have to register an email address, name and date of birth, those posting messages can choose to do so anonymously. A spokeswoman for Ask.fm said: 'Hannah Smith's death is a true tragedy; we would like to convey our deepest condolences to her family and friends. We have reached out to the Leicestershire police and would be happy to co-operate with their investigation into the true circumstances of her suicide. 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. Mr Smith, 45, a lorry driver, called on David Cameron to put regulations in place on social networking websites such as Ask.fm, to try to prevent another tragedy. He is urging the authorities to close down the site, and those like it, after stumbling across cruel taunts from so-called 'trolls' which he said drove his daughter to take her own life. He told the Leicester Mercury: 'Websites like this are bullying websites because people can be anonymous. If I had not spoken up about this, another teenager could be dead next week. Tributes: Bouquets of flowers pile up outside Hannah Smith's family home in Lutterworth as friends and neighbours pay their respects Heartbreak: Hannah's father David receives a bouquet of flowers on his doorstep in the wake of the tragedy 'Ask.fm and sites like these are making millions out of people's misery and it is wrong. I would appeal to David Cameron as a Prime Minister and a father to look at this to make sure these sites are properly regulated so bullying of vulnerable people like my daughter cannot take place. 'I don't want other parents to go through what I am going through.' Hannah's father described his devastation over his daughter's death, who many described as popular and bright. He said: 'We sleep downstairs now, we don't have a bedtime. Since this happened I have only had three hours' sleep a night. Hannah was a bubbly, happy person. She was colourful, she was a normal teenager and was very, very happy. For Hannah to do something like this... We never saw any signs of her doing this. I have now got to concentrate on burying my daughter. I need to be left alone to bury her and to grieve properly for her. Nora Parker, headteacher at Lutterworth High School, said the staff and students were deeply upset at hearing news of her death. She said: 'The governors, staff and students of Lutterworth High School were deeply shocked and saddened to learn the news that on 2nd August Hannah Smith, a Year 9 student, took her own life. Online abuse victim: A Facebook tribute page for Hannah Smith, 14, has attracted 80,000 likes - although a cruel minority had been posting abuse Hannah, who just completed her final year at the school and was looking to transfer to Lutterworth College in August, was a bright, bubbly, popular and thoughtful girl who was liked and respected by all those she came into contact with. She had everything to live for and her family, who are utterly devastated, are at a loss to understand why this has happened. Organisations that tackle bullying called on internet service providers to work with Government, police and schools to address online abuse. Emma-Jane Cross, from campaign group BeatBullying, said: 'We cannot stand by while innocent children lose their lives. We want internet service providers, schools, Government and the police to come together and produce a UK anti-bullying strategy, to prove that this kind of behaviour will not be tolerated. Peter Wanless, chief executive of the NSPCC, said: 'This is a tragic case where Hannah felt like she had no other option but to end her life. The cruel nature of cyberbullying allows perpetrators to remain anonymous and hide behind their screens. This is something that must be tackled before it gets out of hand. We must ensure young people have the confidence to speak out against this abuse, so that they don't feel isolated and without anywhere to turn.' Hannah's death comes amid a growing row about the policing of social media after rape and even bomb threats were made to high-profile female media personalities on Twitter.
