Hi.

You can gather IP addresses from your raw log file. We have a list of "trouble" IPs and run a check against those.

Most of the fraudulent orders we've had will contain "fishy" information, such as mismatched addresses, invalid phone numbers, free email addresses (hotmail) used in registration, etc. This isn't foolproof, of course, because sometimes there are reasons why addresses don't match (ie: Joint venture. One person pays for hosting, another person registers.)

When in doubt, you can always verify the order by telephone. We've done that a few times when things didn't seem right.
