What can be done to fight an outbreak of online threats and bullying in the UK?
British Prime Minister David Cameron has called for a boycott of sites that allow cyberbullying, while asking for website operators to "step up to the plate" and show some responsibility.
A number of companies have pulled their ads from Ask.fm, the site where 14-year-old Hannah Smith was bullied before she committed suicide.
British MP Barry Sheerman wants to take action. On News Stream he said, "I would set up a commission and look at the responsibility of people who own and manage sites like Twitter and Ask.fm because they have responsibility."
"I would look at a range of options like a red button if you're being bullied, so immediately it flags you to a counselor - if you are a child - who can give you information, guidance and advice."
"Also, what we need to do is prosecute these people who cause an enormous disturbance to others as much mentally as physically."
