Reply To: Scam Prevention- Verified Seller
I don’t think the responsibility and potential liability would be worth the effort. A photocopy of a license could be doctored easily enough to provide any address at all.
I still believe the easiest method is to have the seller transfer the points first, after obtaining: 1. written confirmation (let’s use emails) of the terms of the transaction, and 2. information to identify the buyer, which Marriott could confirm (name, address, telephone number, account number, email address).
Is this entirely bullet-proof? No, nothing is. And Marriott will eventually get involved if more people become aware of, and start renting points. They will either step in to stop it, or more likely, figure out the best way to monetize the transaction to their advantage (as you have pointed out before, something on the order of 10 to 20 cents per point).
Like reselling points, Marriott does not want to encourage it, but will be determined to make as much money as possible from it if the marketplace demands it.
