I've been recently searching for some very specific keyword stuff, and bumping into a lot of sites which seemed like just reformatted copy-n-paste of stackoverflow and various mailing lists, adding zero value and clogging up the top 100 search results. Now that I see the HUGE number of copycat sites in the stackoverflow_copycats.txt file, I am beginning to understand what's going on. Thanks!
