Call me naive, but how can the cards or gems be passed to another acct? As far as I know, they can't. If items can not be passed back, then there is no problem. If someone chooses to chase stakes, it will cost them a lot of gems for a CHANCE at the stakes...so seems to me this isn't really an issue.

Again, I there is some way that a person can pass items/gems/cards from one acct to another, then I clearly see and issue. Otherwise, different stroke for different folks.
