Cyberbullying involves sending or posting harmful, negative, or mean content about someone online or through digital devices. It can include sharing private information to embarrass or humiliate the victim. Cyberbullying stems from behavioral, emotional, and self-esteem issues in the bully. It can cause victims to become isolated, lose interest in activities, experience lack of sleep, and have low self-esteem. Possible solutions include restricting internet access, monitoring children's online activities, and blocking harassing individuals.
