Hmm. I think it's coming down to a lot of assumptions on both sides of the line. Do you think it would have helped if there was a note somewhere on the fic, like in the header or at the end, politely requesting that people please leave their comments in the entry in question?
I know some writers don't care, and some do, and there's a multitude of reasons for both, which I can see being a source of confusion and miscommunication on the topic.
