Additionally, when a thread is shadowbanned/ghostbanned, there is nothing for other readers to see as well. Only the creator, yourself, or possibly moderators can see. The public will not be able to see, so links to it serve no purpose. I'm just saying what I have personally observed, so don't know all the history or the behind the scenes. If something doesn't publicly exist anymore or is not accessible, there is nothing there for other readers to make up their minds about.
I don't know what you mean by shadowbanned/ghostbanned but everything remains visible to users who have 'showdead' turned on in their profile. This is in the FAQ: https://news.ycombinator.com/newsfaq.html.
> there is nothing there for other readers to make up their minds about.
On the contrary - if people mention specific links, we can say exactly what happened to that link and this would allow readers to make up their own minds. Most "I got banned/censored" claims never supply the link because then they get to tell a one-sided, and usually entirely distorted, story.
Agree that the OP should be able to provide a link to the shadowbanned thread (if they're not having trouble doing so), because of course you will be able to see it. The context of how shadowban or ghostban is used, is debatably valid. Because the user can see the thread, but it's no longer obviously available to the public.
As for showdead, seems doubtful that many would have it turned on or even be looking. Once a thread drops out of sight (likely top 100), seems most won't check (even more so if no comments) unless they are searching for something specific (which could be anything).
Possibly a good example of shadowban/ghostban thread, is this recently posted one (below). It also doesn't show as "dead" either, though maybe there is some time element, and can't be seen by the public.

Re https://news.ycombinator.com/item?id=34838236: that got hit by a simple spam filter. Clearly it was a false positive (another tradeoff—no spam filters without false positives). Sorry! I've restored it now*. The funny thing is, I was just looking at that particular filter this afternoon and realized it might need some work—I just haven't had time to review it yet, which involves looking at everything it has killed recently and evaluating whether it's still doing more good than harm.
* ("Robot war dogs" is linkbait though, so I've taken that bit out of the title, as the site guidelines ask - https://news.ycombinator.com/newsguidelines.html)
It's true, a lot of this stuff doesn't explain itself and HN can be particularly cryptic. We try to make up for that by answering questions whenever people have them.
I don't mind answering questions (if you have one?) but I need links. Also, links let any interested reader check what happened for themselves and make up their own mind. That's important, since the community is the jury here.
Edit: ah ok, you mean https://news.ycombinator.com/item?id=34853852. I've answered there.
Anyone who wants to check https://news.ycombinator.com/submitted?id=unknownaccount with 'showdead' turned on in their profile can see this for themselves.
I don't know what you mean by "the Fischer link" but the way this works is that we take away submission privileges from an account when they've been submitting too many off-topic or bad (for HN) things, and that causes the software to kill future submissions. So of course there was a time lag between the time that we did this and the time you noticed it—there always is.
Btw, I didn't say "unsubstantiated" but "unsubstantive", meaning that the posts you were submitting didn't contain much information (https://en.wiktionary.org/wiki/unsubstantive).
