Father in bid to shut down ask.fm after his daughter becomes third teen suicide

The father of a teenage girl who killed herself after being bullied online has called on the British Prime Minister to look at social networking websites where users can be anonymous to try to prevent another tragedy.
Dave Smith said his 14-year-old daughter Hannah died last Friday after being “cyberbullied” on the question-and-answer website ask.fm, which allows users to send messages to one another without their identity being disclosed.
