A fairly inexpensive and easy to implement fraud screening service is maxmind minfraud.
It's something like 0.005 per transaction methinks. Another method I didn't see in the thread was doing an email confirmation before performing the cc transaction. Like send an email to the user with a unique ID the user must click to verify a legit email address was used. Can still be bot'd but requires a bit more work on their part, which might be enough discourage since there are a lot of other places for them to go do their dirtiness.
