I was thinking about duplicate content and then suddenly thought there are 136 sites that so obviously have duplicate content : http://www.google.com/supported_domains Haha i bet they filter out their own site :tongue:
Haha! I simply not figured that out before. It can be also Yahoo having duplicate content. Or simply all SE sites violate their own rules having numerous mirror sites. LOL
Its funny but its the reality, we can't blame them for having those mirror site in able to get on the top searches. Other than Google there are lots of site who do that though I am not sure how many of them are. All i know is that they are all cheaters.
