I’m sure everyone must be aware of the famous episode where Matt Cutts’ blog -http://www.mattcutts.com/blog/ (a Google’s employee) was replaced in rankings by another blog using contents from Matt’s blog.
This process of called Google Wash, where site using your content (duplicate entry) to gains ranking and your site is pushed/removed from the search results. This definition is in contact to the current episode. 
The entire work was done by a French team - Dark SEO Team. They wrote a letter (Open Letter to Matt Cutts) to Matt explainin’ what had happned and where Google went wrong.
The post from Matt’s blog dealt on the recipe of bacon polenta. Earlier the top ranking was from Dark SEO Team. Though Google has now managed to get his employee’s blog anagin on Top.
One strange thing you will notic is that Dark SEO Team’s website http://www.pr10.darkseoteam.com/ is PR10. But if you see their cache page through your Google Toolbar the cache page is that of Google’s home page. http://www.google.com. So this team from France have showed to the world that how people can Fake Page Rank 10.
So they have managed to hack Google’s PR for their website.
Anyway so now debate is on as to how Google is or rather is not able to ditinguish between the original content and duplicate contents.
Google definitely needs to take this twist in his story and make something out of it.
