I came across a "Protected by Copyscape" banner in a writer's blog and was curious enough to check out the service. From their About page:

I've heard mixed reviews about this service -- has anyone used it? I tried it with pages from my site but didn't have much luck because of my site layout: because I have navigation sidebars that repeat throughout the site, Copyscape kept picking up that text so the results always gave me my own site pages. I was using the free service, however, so was only seeing the first 10 results.
Anyone else have luck using this service?
