Yes.

At $DayJob we have a similar process [e.g. Accept any card that passes the checksum, hand out rejections on a 24 hour delay after we've handled our fraud signals and processed the charge with the gateway]

The credit card processors aren't particularly interested in handling this for you and you [the merchant] pay the price if you gave the processor stolen card numbers.

Services like these:

would have no customers if you could get a reliable partner to handle this all for you for free-ish.
