Scraper Duplicate Content Sites - Do they affect your search rankings?
In short no, the worse that could happen is that you get frustrated another website has stolen your work and repurposed it as their own. I currently have atleast 50 scraper websites with my content on them, be it abstracts of my blog posts or complete rip offs, however none of them have affected my rankings on Google (I don’t really care about Yahoo or MSN Live to tell the truth).
