ethical question

[griffon512]

i don't think you can look at the ethical responsibilities of the seller on a standalone basis. there are ethical considerations for the buyer too. the buyer should be taking reasonable steps to do their own due diligence and understand the risks of relying on a third party service if that factor weighed heavily in a purchase. it is not the sellers ethical obligation to inform the buyer of these risks in these instances in my view.

time passage is also an important factor. there is a big difference between a transaction between rescinded the same day versus after an extended period of time. in the latter case, the seller will not know if the purchase was made as a resale opportunity that did not work out. aside from that, there are valid reasons refunds have a time limitation across all businesses.

with all of that said, the people i interact with most in the hobby try to do the "right" thing for the buyer and seller where "right" has little to do with legal obligation.
