Same.
Dublone also brings up a very good point on alt accounts. You basically get a 10% increase on amount of gold and and a 10% discount on packs, which is obviously good and cheap.
A method to solving this might be requiring email addresses from here on when people make accounts. Yes, I am aware that you can create different email addresses also, but at least it will require a bit more work to get the cash.
Tracking IP addresses might also work, but then again some people change their IP addresses on a scheduled basis, so that really doesn't work either.
My last suggestion is to change the reward. Maybe you should make it default cards or something similar?
