It seems like this could be discovered through even the most cursory of antifraud team efforts by doing something like a simple database search for ship-to address and then ranking the output sorted by number of orders per US Postal-unique address. Then you review the customer name/payment entity and discard any well known large wholesale customers who might be legitimately ordering a large number of separate transactions to the same delivery location.
