While I do not buy and sell characters etc for real money. I do know how many do. I think if you ban it (or attempt to) that it wouldn't do much more than take the advertising for those trades off the wurm forums. With them on the forums it at least lets you see a bit more about the person you are buying/selling to. While not protected, so to speak, you at least can see if they are doing other trades to know if they are semi safe or not. I think if a way was found to stop some of it that you might lose some of the players that do participate in the market this way. Will it gain you more? I'm not sure it would but that is just my opinion.
