Pay no mind to it, it's just the nature of the internet. People get some kind of confidence from being behind a computer screen where no physical harm or retaliation can come from their attacks. One can only empower them by reacting to it.
The only reason I still haven't beaten up two of my class mates is because I don't want a criminal record or to be kicked out of school. Otherwise I would have loved to grab them by the hair and smash their faces into the wall until they bled.
Ok, calm down. You have to be aware this is the internet, there has some awareness to it: [link]
and that mostly there is nothing you can do about it, other then to block or ignore and just raise more awareness. Usually the gratification of not just cyberbullies but also trolls to react to the bullying or practical joke.
Its not really violent as I though you would, but cyberbullying can escate to thoughs of suicide. ANy type of bullying and putting a bandaid on it saying kids are just being kids isn't really going to help. But really, cyber bullying is too small to be something concerned about it.
