British Prime Minister David Cameron has urged Internet users to boycott certain social networking sites, after a teenage girl who was bullied online committed suicide.
Cameron on Thursday described the death of 14-year-old Hannah Smith, who hanged herself last week after receiving abuse on the website ask.fm, as ‘’absolutely tragic’’.
"There's something all of us can do as parents and as users of the Internet and that is not to use some of these vile sites," Cameron told Sky News television.
Cameron also urged website operators to do more to stop them from being used as forums for bullying.
"The people that operate these websites have got to step up to the plate and show some responsibility in the way that they run these websites," he said.
Some charities in Britain have called for tighter regulation of social networks.
Internet abuse has hit the headlines in Britain in recent weeks after several women, including two lawmakers, received rape and death threats on Twitter.
Ask.fm has described Hannah's suicide as a "true tragedy" and pledged to work with police investigating her death.
It stressed that it encourages users and their parents to report any bullying.
The website, which is popular amongst teenagers, has a question-and-answer format and allows users to post messages without their identity being disclosed.
The ninth most popular social networking site in the world created in 2010 and based in Latvia, has 13.2 million daily users.
