It would be useful to get a list of all this abuse so that we can see how big the problem is. Of course, just because all this abuse appears to be coming from so called "cybernats" doesn't mean it really is. If it bothers you so much, you could always report it to the police so that they might track down the culprits and deal with them accordingly. If this abuse actually exists the people doing it might not be as "hard of thinking" as you seem to think they are.
