Guess this is a good reason for repairers/resellers or buyers to ensure activation status on any Apple device they get their hands on. Easy for repairers/resellers to ensure since they tend to be directly in contact with the company and make it policy. For general buyers, they have to be proactive before making any purchases over an Apple device. As it's easier to contact the seller in question while they are actively selling vs hoping they'll respond post-sale.
