If you don't want to review your transactions on a regular basis then you are never going to be able to get this under control, there just isn't any other way.
If you want greater control and visibility then you need to use Netbilling. CCBill is a great start but Netbilling has better features for being able to tune your fraud filters. As far as I know CCBill has none.
Also whenever you setup a filter to block potentially fraudulent transactions you are also going to be blocking a certain number of legit transactions as well. If you make it so tight that only positively genuine transactions can go through then your sales are going to drop like a rock, because there will be many genuine sales blocked as well. Once again, review your sales transactions daily, at least weekly if you are particularly lazy. I do mine every day over coffee and my various sites are doing over 100 transactions a day between sales and rebills. It doesn't take that long to scan down the list, and you learn a lot of things about your customers and affiliates you wouldn't know otherwise.
