I've never understood the rationale for GSP, especially since sellers can print their own intl. labels, and then simply hand their package to the mailman. Gone are the days when handing an intl. package over the counter was a requirement.
Historically speaking, my observation was that for most international destinations there was no online viewable by anyone proof of delivery. So, any buyer claim for INR was an automatic win for the buyer. The delivery confirmation was required for seller protection even though it was not possible to obtain. So the risk was on the seller. When the online payment became a requirement, we could no longer get those crisp USD bills in the mail.
After a few rounds of losing at ebay roulette, sellers who could not afford the losses simply would not ship internationally anymore, or limited it to certain countries or customers. Thus the birth of the "reshipper" services. When these services first started it was a disaster since so many parcels arrived at these US addresses per day, scanning them delivered simply was not done. US addresses associated with too many INR claims were avoided like the plague, and seller simply checked the box in paypal to only accept payments from US accounts. The services got better at it in time, and business was good.
eBay wanted a piece of that action, so started the GSP program with the statements and terms quoted up thread. They had a hard time getting volunteers so ebay would opt us in every once in a while, or slickly add it to the new user agreement.
It is true that more contries have appropriate delivery confirmation. Now, however, we have the issue of having a SELLER pay for a return for SNAD or being part of the free returns program so international selling on eBay becomes even less attractive to some sellers.
