Update: "Fu.org" still hasn't removed the post plagiarized from my site. But as I've been trying to fight this, I've found two helpful things you can do if you ARE plagiarized:
1) Go to the Technorati Home page (www.technorati.com). Select "Contact Us." You will see a window that says "Message type ..." From the pull-down menu, select "I see a copyright violation." I did this months ago with another plagiarist, and the plagiarist removed the offending post with days, though I don't know if the Technorati complaint was the reason.
2) Look at the Google AdSense ads being sold against your plagiarized post. Click on the ads, then use the companies' contact forms to get in touch and let them know their ads are appearing on sites with plagiarized content. One of the ads sold against my plagiarized material was for a well-respected college, which I am sure would be mortified that is is happening.
Thank you so much for all these helpful comments.
