There was a problem with misconfiguration and you have taken advantage of it. You have bypassed a normal way of claiming coins and this misconfiguration allowed you to do it. I think you know very well you have claimed more coins than you were allowed.
I used the most obvious way to claim, how could there be a more "normal" one? And all my payments were about $0.50, I don't have anything more. If you missed any coins, look who was my so-called "referrer" in your (mis)configuration, that wasn't me to take any advantage.
