spammer getting around user verification with Gmail

We’ve installed your plugin and are still having issues with a card phisher getting around the email verification. They enter what appears to be legitimate name and addresses, the email is always formated as FirstNameLastname.######@gmail.com. The numbers are always different however there are always 6 numbers.

We’ve tried using pop-up and also in-line and neither seems to stop them. They get on, try to enter an order to validate the card which then fails the order. (Occasionally, they get a good combination and an order and payment is actually generated, however this is rare)

How do we stop these guys. I tried a HoneyPot trap and they stilll get thru that which tells me it is probably humans who are trying to validate the cards

Suggestions?
