Dan Thies published a post about how people have been hacking Google's search results using proxies to get the original sites nuked as duplicate content. He also explained how to defend sites against the problem using free PHP scripts developed by Jaimie Sirovich. Dan Thies stated he thought many of the proxy hijack accidents were not accidents at all:
Of course, not all proxies are being run by innocent people for innocent reasons. Some of them are actually designed to hijack content - to deliver ads, etc. Some people want to steal your content, and they want the search engines to index it. In fact, I would not be surprised if a large part of the overall problem isn't caused by such people firing links at their own proxies.
I have seen numerous sites die to proxy hacking, and this is an issue Google has known about for over a year.
Yet another reason hand edits at Google coupled with Google paying AdSense scrapers to steal your content makes Google a pretty dirty company, especially when you consider their unofficial stance on copyright:
Your name can not be stripped and no one else can claim credit for it. That is credit, reputation is a non renewable resource. It can not be replicated. It can not be copied. To the degree that someone takes credit for your stuff, that's the degree to which you lose credit. It is always proportional.
When Google goes so far as trying to police link exchange and link buying why don't they do a better job policing AdSense? If they want to clean up their search index the easiest, most scalable, and most robust way to do so would be for them to worry about their own network, and stop paying content thieves via AdSense.
