tell me the first 15 digits of your cc and ill tell you the last one, they arent random numbers.

no one is suggesting that. dildozer is suggesting charging/authorizing a credit card in order to confirm age and get access to the site (like a paysite or free trial site).
in order for an authorization to be approved on a credit card, the card number has to exist.
the check digit may not be random, but the checksum algorithym is worthless if the first 15 digits i give you are fake.
