There have been concerns from some users that we have let exploiters go too easily. Stand assured that we handle all exploits very seriously. Exploits vary in size and extent and on global impact on the game. Some exploits are such that many people actually do them inadvertently, while others systematically maximize their profit from them. On a case-by-case basis, we decide what to do with the exploiters, but the usual punishment is permanent ban from the game.
We have recently uncovered some networks of exploiters, many of them linked to online auctioning of credits and items. We have taken tough action against those and all those that were directly involved with them. All their accounts have been closed and all personal ( in game ) as well as corporate properties confiscated.
Soon we will publish a more explicit banning policy, so that users are well aware of the repercussions of their actions.
