ArenaNet Clarifies RMT Policy
Gold selling = bad.
The Arena Net team, which makes the Guild Wars game, has announced their official stance on real money transactions and gold sales.
It is our goal to provide an enjoyable experience to every Guild Wars player. That's why we take the topic of real-money trading (buying and selling gold or in-game items for real-world money) very seriously. Every week, we ban thousands of accounts used by real-money trading companies, because those companies harm the game for other players by running large networks of bots to farm gold and items, spamming chat channels with their advertisements, and even attempting to steal login credentials from unsuspecting players.
