Well read the EULA. http://dust514.com/eula/ 6-B

B. SELLING ITEMS AND OBJECTS
Within DUST 514, you may be permitted to transfer, trade, auction, sell, buy or otherwise accept virtual goods and other content appearing within the Game, including without limitation character attributes, items, currency, and objects, but excluding characters themselves (which may not be sold or transferred from their associated Account). All such transfers must occur within the Game environment, and may not be transferred, traded, auctioned, sold, purchased or otherwise accepted outside of the Game environment. In addition, you may not transfer, trade, auction, sell, buy, or accept any offer to transfer, trade, auction, sell or buy any content appearing within the Game environment, including without limitation characters, character attributes, items, currency, and objects, for real world currency. You may not encourage or induce any other person to participate in such a prohibited transaction. The buying, selling, trading, auctioning, or other transfer (or any attempt at doing so) of characters, character attributes, items, currency, or objects outside of the Game environment or for real world currency, whether through online auctions, newsgroups, postings on message boards or any other means, is strictly prohibited by the EULA and a violation of CCP's proprietary rights in the Game. Unless otherwise prohibited by applicable law, you acknowledge that any revenue generated by you in violation of this section constitutes proceeds from the sale of CCPGÇÖs proprietary property, and that upon demand of CCP, you shall account for and pay over to CCP all such revenues.
