I recently spotted an editor linking a release to a secondhand eBay listing using the “purchase for mail-order” relationship. I am uneasy about this, since in my understanding eBay is an auction site and therefore any purchase links will expire after the auction ends. That appears not to be the case here (disclaimer: I do not use eBay and am therefore unfamiliar with how its system works), though the same issue of link rot is still applicable. Should eBay links be allowable as “purchase for mail-order” links?
