Yeah, I saw the tail end of all that. One difference is that newsgroups don't have the same precise threading that HN does. I would be okay with not only killing comments on a per user basis but also killing all replies to those comments. So don't show me any submissions that SparrowOS makes, don't show me any of his comments, and don't show me any replies to those comments. Conceptually easy, but perhaps expensive in some cases such as looking through another user's comment history.
