The first starts with: Thanks for your response. The second starts with: Hey, do me a favor And the third starts with: I had no idea HN censors
If you can see all three - then you can also see the censorship by starting a private browser and looking at this story.
There will only be the second and the third.
I've tested in private sessions on firefox and safari and through a few different ip proxies.
I'm going to do some testing in other stories/comments to see whether they detect words, or general sentiment. And I'll get some statistics on if this is predictable censorship, a one time deal, or whether I just hit a race condition in their code somewhere.
Maybe hit up hn@ycombinator.com and ask to remove your shadowban of sorts. Idk how effective is that.
Anyway something more concerning is that you have at least two flagged comments (in the first page at least). Flagged comments means your comments violated HN rules, at least according to other HN users. It's hard to understand the HN social etiquette but in short, if you are being mean to other people, you might get flagged. So it's largely about the tone of your comments rather than their substance. You may want to read the guidelines (the section "in comments") here https://news.ycombinator.com/newsguidelines.html
