I'd have to agree with Dropkick, there's always a way to avoid or get away from it.
Even here on the toribash forums, say someone like Gorman (continuing your example) decided to follow you around, you could always post in your clans forum and let them know that since they aren't part of the clan, they shouldn't post. From there it's taken care of. If you don't have a clan and you post in discussion threads, then the best they can do is find rebuttals for your points, which is the main focus of this. Outside of that, all you'd have to do is switch to a new thread.
On facebook, they have preventive measures about this, mainly, the blocking of a certain person. Also, since it's usually looked at as a "serious" issue, you could easily report the name and that person would be contacted or the account dealt with.
Facebook being the most public networking site I can think of, all other sites would be easier to deal with than that one, thereby eliminating any difficulty in dealing with cyber-bullying (assuming you don't sit there and cry about it).

Onto the topic of whether or not it's right or wrong.
Either or, some people get a kick out of it, and some don't. As there are simple measures to be taken to stop it (stated above) those who do not like it, don't have to deal with it. Those who do, can. From there, it is up to the individual to accept the risks of using the internet. It's the same as, say, going outside. There are people in real life who will target people for no other reason than to amuse themselves, but is it taken as seriously as cyber-bullying? Nah, it's just pointed banter at that point, but put it in text and hot damn, you've got a thirteen year old committing crimes.
I understand that the world is tending towards an "online culture" but that doesn't mean there should be stricter penalties for things done online.
