Sir: Cyber bullying has increased with the use of social networking. When the internet is used to hurt, embarrass, or threaten a person, cyber bullying occurs. It exposes victims’ personal information on the internet for the purpose of intimidation or threats are made on social networking sites. Cyber bullying has become a problem on social networking sites; in some cases people harass others to the extent of threatening them with physical harm. Studies have shown that almost eight percent of teenagers and 18 percent of middle school students are victimised by internet bullying. Students become victims of low self-esteem, suicidal thoughts, and absenteeism because of cyber bullying (Meredith, 2010). People should be made aware of cyber bullying and taught about the safety measures that could help. Parents and children should be given guidelines about appropriate online behaviour, which includes interacting with unknown individuals on these sites. Many children have lost their lives because of cyber bullying. One example is a 13-year-old who committed suicide because of an online prank. Classmates pretending to be interested in him had teased him at school and when he approached a girl, whom he thought liked him, she turned him down, telling him he was a loser, and that she did not want anything to do with him (Meredith, 2010).
