This is the wrong way to approach the problem. Hosting costs very
little, whereas processing credit card numbers costs the merchant a
significant amount per transaction.

Being on the other side of the hosting issue, you are more likely to
hurt the provider than the spammer, as they generally use fraudulent
credit card numbers themselves when signing up for the services.

Legal issues aside, you could write a script that submits many orders to
the website, using trivial credit card numbers that checksum correctly
but will not pass validation (eg, all 0's). Even if they have used
stolen credit cards to pay for the credit card processing, it will (or
at least, should) attract the banks' attention when so many denied
transactions are processed against their account.
