I believe a conspiracy (in the legal sense) requires communication - peer pressure doesn't.
Edit to add: if you're going to argue legal conspiracy, you're going to have to provide evidence that isn't circumstantial. Russell's Teapot, and all that.
That's user actions (admin results in "dead"), though HN may be tuned more sensitively, particularly for a highly-active green (new) account. Prior history may be associated. Recent days (and months) have been fraught.
There's a contact email in the FAQ. You can request action, though that doesn't seem overly justified here. Guidelines are also worth aa review.
Discussing voting is strongly discouraged.
Emotion runs high on political threads. It's useful to carefully consider what you write, how much evidence you present, plausible alternatives, and tone.
For future reference, when that happens just do one of these:
1. Wait a few minutes. HN does not allow immediate replies to new comments. This is the preferred solution.
2. Click the timestamp on the comment to get that comment on a separate page. On that view you can reply even if the comment is in the "no replies yet" window from #1. (I'm not sure if this is a bug or a feature).
