Google's new patent for identifying manipulated articles:

Google's Monika hensinger and Alexander Mark have identified a new algorithm to detect manipulated and duplicated articles. I feel this will be a big hit for all SEOs who use
article reproduction as part of their service/ SEO strategy. Article reproduction has been there for a while as an important and search engine friendly strategy for optimizing
sites. We are not sure how long it will last. We might post our review on this article soon
