Facebook worst social networking site for bullying

A study has suggested that Facebook is the worst social networking site on the internet for trolling and bullying.
87% of reports of cyber abuse cases happened on Facebook while one-fifth of cases were on Twitter.
The report suggested the most common victim of this bullying was 19 year old boys.
Only 37% of victims of cyber bullying reported the incident to the Social network site when it occurred. This low number of reported incidents shows that many people are suffering in silence.
