I suspect there was a human who posted a link to the OP's post here on HN. It is -that- human who was being asked to provide context since they should have know that by posting a link to HN, they are posting a link to a community that may be different from the OP's original audience.
i.e.- this was not a rerquest or taner saner to provide context, but a request for @ericdiao to provide context.
