1. Cyber bullying is repeated and relentless harassment over time using the internet as a medium. The general object is to make the subject feel demotivated/insulted.
2. I have, but not in the sense that my friends on Facebook are talking smack about me
3. Traditional bullying is more in your face, you know when it's happening. The damage is more physical sometimes, but it's generally as mentally damaging (if not more) than cyber bullying.
4. TF.TV is a massive site full of groups of idiots talking shit about people they don't like. It's not cyberbullying at all
5. It would decrease it, but the stuff that actually matters is when people are ganging up on others and making it known. If you give someone a name, they becomes more stressful.
