I was wondering if anyone knows what Netflix cross references to see if you already used the one month free rentals.

CC
Address
Name

I know the coupon, and in their site, says you can only use the promotion once. But has anyone tried to do it again???

Hence, I have another CC, or could get someone else in my house to sign up. But if they cross reference address, then no good.

I would imagine it would have to be by name and email. If it was by address, it could cause problems in homes with roommates and borders, ect..... I am not positive on this, perhaps they don't care or didn't think about this posibility. Also if it was by address, how would they take into account when people move?
