I don't like the mob thing either but it's how large group dynamics on the internet work (by default). We try to mitigate it where we can but there's not a lot of knowledge about how to do that.
It's ridiculous that this impromptu feedback session is happening here in a sub comment of a trivia thread that many users will just overlook. Feedback and community engagement should be an ongoing, (semi-)formalized process, not an ad hoc, once in a blue moon type of thing that will have been buried under a deluge of garbage by tomorrow morning.
It's really weird how two of the most important platforms of the open source world (HN and GitHub) have no feedback process in the commonly accepted sense. Every niche Python package has an issue tracker nowadays where problems are collected, discussed, and often resolved, with the synergy of the community of users. But the grand systems underlying all of this are somehow exempt from needing anything like that, and "email the moderators" is good enough? I don't buy that, sorry.
There are many variations of this feedback system, but comments randomly interspersed in unrelated discussions, never to be found again, is not one of them. And neither is a private mailbox.
I'm also not sure that an internet forum like HN is a good fit for the issue tracker model—but that could just be rationalization on my part.
Don't you get tired of answering the same questions again and again, and rebutting the same arguments year after year? I can't imagine not being able to just write "Duplicate of #3845" and close the issue.
Oh yes - it's probably the worst part of the job. But I think it's necessary for community because people respond differently when they're getting personal attention.
It's still my intention to build a canonical set of explanations for each common question and then mostly refer people to those. I've inched toward that over the years via HN Search links to my post moderation comments (which I know can get a bit annoying).
Even then, though, the mechanism will just be standard comments in ordinary threads, because that's how conversation takes place here, and people will always want to have personal conversation with the mods.
Users also tend to respond better when they get a detailed explanation of specifically how their post(s) broke the guidelines. Unfortunately, that sort of explanation is super expensive to produce—in time, energy, and stress. I don't have what it takes to do it in every case, which is a pity, because it tends to work. Here's an example from the other day: https://news.ycombinator.com/item?id=35403143.
Long term, we need better feedback mechanisms to let people know that they've broken the rules, and which rules, and for how long they might be in the bad dog box.
