Cyber-bullying involves the use of digital technology to repeatedly torment, threaten, harass, humiliate or embarrass another person. It can have serious psychological and emotional impacts on victims and in some cases has led to suicide. While some states have laws against cyber-bullying, there is no overall federal law. Schools can educate students about cyber-bullying and enforce rules against harassment, while parents should talk to their children about signs of cyber-bullying and encourage them to tell an adult if it occurs.
