The suggestions are good for physical, one-on-one contact. When it happens over the internet, even removing yourself from the situation does not stop the bullies. In fact, they feel more emboldened because they think what they did chased you away.
Bullies don’t only lurk in school hallways and playgrounds… They grow up and become parents, co-workers, and bosses. They work in offices, businesses, for governments, in police departments, law offices, and charitable organizations.
Studies show that cyber-bullies really are sadistic and have narcissistic/psychopathic personality disorders. This is true of many garden-variety bullies as well.
