The Internet has created a whole new world of social communications for young people who are using e-mail, websites, instant messaging etc. to stay in touch with friends and make new ones. While most interactions are positive, increasingly kids are using these communication tools to intimidate others. This has become known as cyberbullying.
    Today’s young Internet users have created an interactive world away from adult knowledge and supervision. Because bullies tend to harass their victims away from the watchful eyes of adults, the Internet is the perfect tool for reaching others anonymously. This means for many children, home is no longer a refuge from the cruel peer pressures of school.
    Nancy Willard of the Responsible Netizen Institute cautions that technology can also affect a young person’s ethical behavior because it doesn’t provide concrete feedback about the consequences of actions on others. This lack of feedback minimizes feelings of regret
    There are several ways that young people bully others online. They send e-mails or instant messages containing insults or threats directly to a person. They may also spread hateful comments about a person through e-mail, postings on websites or online diaries. Some steal passwords and send out threatening e-mails using an assumed identity.
    Schools are struggling to address the issue of cyberbullying among students. When real world bullying occurs in a schoolyard, teachers are often able to intervene, but online bullying takes place off the radar screen of adults, making it difficult to detect in schools and impossible to monitor off school property.
