This is a shameless plug for a post on one of my other sites:
A few weeks ago, I had the dubious honor of being plagiarized. One of my best articles from one of my other sites was re-posted verbatim without notification, permission, or attribution, as the very first post on a brand-new blog.
I knew this was illegal, but wasn’t quite sure how to handle it at first, so I sought guidance from the Google God, and found some excellent information and tools for dealing with plagiarism. After I resolved the situation to my satisfaction, I wrote a post detailing what I learned and how I used it to take down the offending post. Click here to read the entire article.
