It does seem to me that this isn't about rendering a service, or making the world better. Instead, it is about petty vengeance and self-righteousness.
I have thought for a long time that this search engine poisoning will grow increasingly out of control, and it will eventually have increasingly dire consequences.
It could be used in another way. What's to stop some of these people to take individuals they don't like, start a blog while using something like TOR, and ruining their reputation with horrible allegations that cannot be taken down no matter what, cannot be traced back to their original perpetrator, and could show on the first page of major search engines for a good chunk of the rest of their lives? Even doing it to all members of their family? I am sure that something equally nasty will happen to some of the Jezebel people.
The bottom line is that vigilantism and public shaming is never a good idea, because it can very easily be abused, and ultimately all that it does is cause escalation. We will also have some questions to ask ourselves as a society on how easy the Internet makes it to publicly shame someone or assassinate someone's character for any reason. I cannot foresee such a free-for-all environment continue perpetually, ultimately the law will catch up, because at some point there will be so much savagery and viciousness that it won't be sustainable.
