I would personally say that it has nothing to do with being a Moderator. You insulted a programmer (intentionally or not, isn't particularly relevent.... if it wasn't intentional, you probably should have apologized). The only thing she did as a moderator, was lock the bumped post, which hardly constitutes an abuse of moderator power. Had she edited your post, or deleted it, well, ok, but she didn't. This is a person to person battle, and her status as a moderator has nothing to do with it.
