Apparently unable legally shut down two most popular pirate online libraries — http://www.flibusta.net/ and http://lib.rus.ec/ — Russian copyright fighters trying to go in different direction — cover them up from regular users.
Sites becoming not accessible directly from many providers in different countries. But you still can see content and download books with anonymizer — for example: http://anonymouse.org/cgi-bin/anon-www.cgi/http://flibusta.net
