I've been wanting to ask this question for a while now. I operate a large site with a lot of user generated content. We use copyscape constantly to look out for plagiarism, but since copyscape uses Google's search index to find copies, wouldn't the fact that Google has been de-indexing duplicate content mean that copyscape will no longer be able to find the pirated copies?
I would imagine that supplimentals would not show up in Copyscape searches, and I would also think that most scraper-scum sites have gone supplimental.
Just trying to be logical here...
