Here is the deal, I'm running a small website for free ebooks and I'm displaying adsense ads. However I've got there a few favorite books that are copyrighted but are helping me quite a bit put the blog on its feet. I am 100% aware of the adsense policies and I know that this is a violation, so don't quote me the user agreement please! My question is does anyone have any idea how google flags copyrighted material? The only possible way I can imagine is the copyright owner to report me to google. But as I'm too small I don't see this happening. So share your EXPERIENCE and try to be objective what the ACTUAL risk of having like 8% copyrighted material is. We are not talking about freshly published blockbusters, but rather classics with extended copyrights (so not that sensitive for publishers). Furthermore in my About page I have an appeal form for violated copyrights. As an example of copyright material I can give you is "Ender's Game", published 1985. Thanks guys!
