I think people are over-sensitive about cyber bullying. Everytime I watch some presentation about it, I see things that happen to me on the internet 5 times a day.
Someone on the internet calls you a “*************************” because you disagree with his opinion on the new Generic Shooter 16: Nuke Edition =/= Cyberbullying
That’s not to say it doesn’t exists, but those teachers, parents, whoever is making those anti-cyber bullying campaigns are targeting a completely wrong thing.
