I found a website last week that copied 2 pages from my website word for word. They were hosting at freewebs.com so I contacted them and the content was taken down within a week. For my particular situation, it was easy to prove he ripped off my content because he was hot linking my images and he also (like bb1 said) was too lazy to remove my links. He still had links on the page pointing to my tracking script. It’s extremely frustrating when this type of thing happens.
Keep an eye on copyscape, dustball, plagium, and the many other plagiarism checkers online.
