I say this over and over again. There is a difference between bullying in real space and in cyberspace. It's more than just the methods and location. Cyberspace adds the accidental component with things being misunderstood and sent to the wrong person, when a joke doesn't play well and isn't understood as a joke, etc. Unlike offline bullying, not all cyberbullying is intentional. One entire class of cyberbullies, the inadvertent cyberbully, is accidental.
