I wouldn't be entirely surprised if there was a human involved in gathering some of the data. If requests for data are rare enough, it might be more economical to pay someone in a customer support farm to collect some data than to pay for developing and maintaining an automated process. At least in the short term. Otoh, not automating something like this seems out of character for Amazon.
