What law do you think forbids this? In my experience running global payments through multiple rails, on an OFAC/risk ping you typically get a request for enhanced due diligence, which normally looks to the payee like “send me a picture of your drivers license”.
The most common result is that O Bin Laden (matching the OFAC list) is actually Oscar bin Laden; with further info you disambiguate the payee from the OFAC listed entity and are allowed to transact.
I have never encountered a reg that says you are obliged to ghost your customer.
