You can ignore the person you replied to. Do you have "showdead" turned on in your profile? They've written an abusive post about you in this thread, but it got flagged.
I saw. But it didn't make this comment necessarily invalid. If there's a policy against putting an HN post on social media when said post involves the person publicizing it, I'm not aware, and I'm happy to fix it if it's a problem. I knew when I posted it that this made the post more likely to attract trolls (sorry, dang), but I know I'm not the only one that watches how HN responds to this kind of topic.
