The only reason I see for you to be so upset about this is if you are a competitor site, or if you are the owner of those sites and simply want to get traffic there. If not, your time will be much better served concerning yourself with what you do and making your money. Chasing after every wrongdoer in the world only leaves you broke and in your mother's basement.
I totally agree that these people are sleeping. I applied for adsense last week and after 9 days didnt get any message from them. My friend with completely duplicate content autoblog got approved in a day! Bad luck!
