You can automatically reject the card if the AVS doesn't return an exact match on the billing address. You should be rejecting those anyway. That should block 99% of those cards, as they usually don't have the billing address.

Do a pre-auth for $500, whatever your actual value is. That'll blow the limit for 99% of those pre-paid cards and it'll fail. Be sure to cancel or immediately charge for customers for whom the $500 works as otherwise your legitimate customers will unexpectedly have $500 credit tied up.
If the AVS comes back as a match and you've shipped to the billing address...
...and have signed-for delivery then you can usually fight a chargeback without problems.

Why do you want to block them?
I don't know about the OP's situation but many merchants use the possession of a valid credit card as proof of age. That includes legit age restricted products like alcohol, not just "adult" material. One of the reasons for pre-pay cards is to give minors access to eccommerce.

The purpose is because my product is a recurring membership and we pay out affiliates more than the first month payment. I am afraid some might try to scam me for the initial payment and then unable to charge for future months.

We use AVS to process cards and Gift Card type Visas never match AVS no matter what address is put in for billing. They are declined every time. I only let regular customers who have ordered many times from us before use them and then I have to manually override our system check for AVS so they will be accepted.
