I might answer the question with a question, why do our young people need to spend so much time on the computer? Go outside and hang out with the 3 dimensional people. We spend way too much time online and if we are intimidated by someone online--what does that say about how we handle ourselves in life with a real threat.
I think we need to shut the machines off after 30 minutes and find something else to do.
Could anything be more cowardly than cyberbullying?
