You probably can't answer that, but I know I like tweeting about my HN posts and inviting folks over to HN to participate. If that's a bad thing, we need to know that and not do it anymore.
EDIT: Is there is a prohibition against tweeting submissions?
EDIT2: Happy to abide by whatever rules there are, but without knowing them I can see where it could get very frustrating for a lot of folks. A couple of my submissions I was sure were being flagged, but now I'm guessing it's because I shared the link with folks. That's an extremely non-intuitive system response.
