I think cyberbullying is only for cowards as they usually 'bully' people by spreading rumours or display hatred by posting messages. Those people that bully usually are being bullied themselves by other people. Cyber bullying are for COWARDS. In my opinion, people cycberbully is because......
a)They were bullied before. b)They were provoked by someone. c)They bully for fun.
I would tell the victims to stay away from websites such as Facebook. Blogger , Friendster for the time being until they stoping posting rumours.
