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.

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.
Agree that the OP should be able to provide a link to the shadowbanned thread, 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).
