It looks like ref-earnings are not right.. the earning says: You currently have 6 referred users (THANK YOU!) and have been paid a total of 0 satoshi. I dont know why people would join and not play.. Can you even do that? 
Update: Now I have 7 ref´s but still no earning. And on the "gamepage" the ref-link goes to your other site.

Looks like the site accidentally flagged you as a bot due to some behavior that bots frequently use. Resolved. 4 of your 9 referred users started to play a card and then abandoned, never receiving a payment.
