Bullying has never been easier. Any child, operating in relative anonymity on the Internet at any time of day or night, can harass and intimidate peers. Bullying has gone high tech as kids, usually between age 9 and 14, use personal computers, cell phones and PDAs (personal digital assistants) to intimidate and manipulate their peers. Bullying behavior can manifest in instant messaging, cell phone text messaging, online gaming, chatrooms, blogs (online journals), and social networking websites. Bullying used to be confined to playgrounds, lunchrooms, and to the school day. Technology allows cyberbullies to harass their victims after school and on weekends. With children spending hours at a time wired to communication devices, they are increasingly vulnerable to aggressive online behavior. Because the bad behavior occurs off-campus, school districts struggle to identify and punish cyberbullies.
