helpful hint on how to pay if you don't have a credit card..

i enjoy this game so much i'm going to subscribe asap.I don't have a credit card,but i can get a preloaded card to use strictly on the internet.I have read a lot on the subject of deadbeating and probably the best way to deal with it is to put them on your ignore list,or attack the shit out of them!How about limiting the deadbeaters to a max.of 3 armies only ,no matter how many turns they miss.
