Oh, that was me. As such, let me take the opportunity to explain why these posts were not deleted.

In this case.

1. The question was closed when I got around to it
2. It was likely to be roomba-ed.
3. The comments seem mostly harmless.
4. I didn't really see any specific point in deleting stuff that would be deleted eventually anyway and were harmless. The flags did seem somewhat redundant in this view of things, and some of those comments felt mildly enlightening. 

As far as I know, there's been no change in the general policy in comment flag moderation. We read through them, and decide as needed.
