I appologize it took so long to get back to this, we're working on some man-hour heavy things and do to the difficulties in tracking cards after they've been bought, recycled bought recycled, bought recycled, etc, made this one of our biggest efforts for least rewards we've had to deal with for a while.
The solution is this -- for the worst abusers of the bug (This will be a much smaller pool than the pool of users kicked from the event prizes), we will calculate a Gran value that will be deducted from their accounts. This value is something we've put together working backword, and it will be calculated slightly differently depending on the range of pulls and the size of the number will be directly related to the number of total pulls.
Each effected user will be contacted with the gran value ahead of time. If that amount is not availablle, the effected user will have to recycle cards until that amount of Gran is availablle. If you want to be really fair, you can recycle the specific cards you got that day, but to be perfectly honest -- we have no way of knowing. If you think you are in the danger zone and you have extra Gran sitting in your account, you might want to leave it there to save yourself a collossal amount of work. If you are not able or don't want to take the Gran penalty, your account will suffer a suspension.
