Why were bidders from outside the Continental US allowed to bid on my item?

Question

2 bidders from Vietnam placed bids on my item. I don't ship there. It's on my list of unacceptable bidders.

S/he was able to bid/buy because either s/he has a Primary Shipping Address in the US or you didn't set your Buyer Requirements to block those with PSAs in a location you don't ship to (the default for all Buyer Requirements is OFF).

You are not under any obligation to ship anywhere you didn't agree to ship. The buyer can only pay if s/he gives a shipping address in a location you've set up to ship to. If s/he does (many international buyers use forwarding services or friends or family in the US) your obligation is to deliver the item as described to that address, any forwarding from there voids the Money Back Guarantee. If s/he doesn't you can cancel for non-payment after 4 full days.

You cannot preemptively block bidders by country of registration. Perhaps those bidders have US shipping addresses.
