There's no such thing as a comment "disappearing without leaving traces" on HN, except in rare cases when an author asks us explicitly to delete their post and we do. Other than that, the most that happens is that a comment gets killed (a.k.a. marked as [dead]), and anyone who wants to can see those comments in their, er, glory by turning on 'showdead' in their profile. This is in the FAQ: https://news.ycombinator.com/newsfaq.html.

We don't moderate this place to promote (or demote) any particular political agenda, let alone try to "shape" public opinion, something which sounds even more boring than soulless. As long as you're implying secret sinister processes taking place here, I think you should include some specific links so readers can make up their own minds.
