At the forum in the Russian section discusses the installation of mod on a "half-pirate" version of the game (АRMA2 game is downloaded from a torrent, then it's activated by only a ARMA2:OA key). As far as I know this is a dev forum, and main dev of mod, one of the devs of the ARMA2 game. I also heard that he believes that the best support for the Day Z is to buy BI games. How moderator of a forum may create such topics http://dayzmod.com/forum/showthread.php?tid=1725 ? Already many new players with pirated versions, they should be banned! Can one of the developers to express their views?
