Swapping gold/loot between two characters played by the same person, or facilitating in the swapping of these things, is entirely against our rules. We are perfectly prepared to ban for it.
If you wish to continue playing here, don't do it. If you've done it in the past, I suggest letting us know as soon as possible and explaining why we should believe you that you won't do it again.
We're going to be enforcing this a little more strictly, and going back and handing out bans for people who've done this in the past unless we get apology e-mails very fast. And I assure you, we've a LOT of tools that can help us track these things.
