@dang, I think we need an explanation for why Tank Man-related content on Hacker News has been disappearing all day. I usually trust HN to be a bastion of free speech, and if there isn't some kind of proportionate response here, I don't believe myself or many others here will be able to see it that way going forward.

EDIT: Thank you for your response, dang. Hacker News is a special place, which is why we have responded so strongly to today's events - I apologize if the tone above came off as less-than-civil. I (and it seems, many others) look forward to hearing more about the 'dupe' article others have linked to below. It was only upon seeing the article marked as a dupe after seeing the previous flagged out of existence that it began to feel like more than just a user-initiated action, so I am sure further information on the mod-initiated actions will put these fears to rest.

This post is on the front page right now (edit: and now also https://news.ycombinator.com/item?id=27396783) - that's the opposite of "disappearing". I'd have to see links to the other ones.

Here's one tip for you guys, from years-long, world-weary experience: if you're coming up with sensational explanations in breathless excitement, it's almost certainly untrue.

Edit: ok, here's what happened. Users flagged https://news.ycombinator.com/item?id=27394925. When you see [flagged] on a submission, you should assume users flagged it because with rare exceptions, that's always why.

A moderator saw that, but didn't look very closely and thought "yeah that's probably garden-variety controversy/drama" and left the flags on. No moderator saw any of the other posts until I woke up, turned on HN, and—surprise!—saw the latest $outrage.

Software marked https://news.ycombinator.com/item?id=27395028 a dupe for the rather esoteric reasons explained here: https://news.ycombinator.com/item?id=27397622. After that, the current post got upvoted to the front page, where it remains.

In other words, nothing was co-ordinated and the dots weren't connected. This was just the usual stochastic churn that generates HN. Most days it generates the HN you're used to and some days (quite a few days actually) it generates the next outlier, but that's how stochastics work, yes? If you're a boat on a choppy sea, sometimes some waves slosh into the boat. If you're a wiggly graph, sometimes the graph goes above a line.

If I put myself in suspicious shoes, I can come up with objections to the above, but I can also answer them pretty simply: this entire thing was a combo of two data points, one borderline human error [1] and one software false positive. We don't know how to make software that doesn't do false positives and we don't know how to make humans that don't do errors. And we don't know how to make those things not happen at the same time sometimes. This is what imperfect systems do, so it's not clear to me what needs changing. If you think something needs changing, I'm happy to hear it, but please make it obvious how you're not asking for a perfect system, because I'm afraid that's not an option.

[1] I will stick up for my teammate and say that this point is arguable; I might well have made the same call and it's far from obvious that it was the wrong call at the time. But we don't need that for this particular answer, so I'll let that bit go.

We were told the same thing about the lab leak theory from: Social media companies, Mainstream media, and the government.

The reason for distrust is valid. We live in an age of rapidly increasing censorship and the CCPs growing reach of control in American discourse. Skepticism is becoming the default for very real reasons.

I can tell you personally with high confidence that neither the Communist Party of China nor any other Communist Party has influence on how we operate Hacker News. I can't say anything about any other site or company or media or government, because I'm not involved with any of that. But unless the communists are zapping me with behavior-control rays or Angela Lansbury had me brainwashed decades ago, zero such influence is happening here.

You don't have to believe me, of course, but if you decide not to, consider these two simple observations.

First, lying would be stupid, because the good faith of the community is literally the only thing that makes this site valuable. So, sheer self-interest plus not-being-an-idiot should be enough to tip your priors. I may be an idiot about most things, but I hope I'm not incompetent at the most important part of my job. The value of a place like HN can easily disappear in one false step. Therefore the only policy which has ever made any sense is (1) tell the truth; (2) try never to do anything that isn't defensible to the community; and (3) acknowledge when we fuck up and fix it.

Second, if you're going to draw dramatic conclusions about sinister operations, it's good for mental health to have at least one really solid piece of information you can check them against. Otherwise you end up in the wilderness of mirrors. What you see on internet forums—or rather, what you think you see on internet forums, which then somehow becomes what you see because that's how the brain does it—is simply not solid information. Remember what von Neumann said about fitting an elephant? (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...) He asked for a mere five degrees of freedom. Nebulous internet spaces give you hundreds at least. That's way beyond enough to justify anything—even dipping in a ladle and getting one ladle's worth is enough to justify anything.

(Edit: people have been asking what Angela Lansbury has to do with this. If you don't mind spoilers, Angela will explain it for you here: https://www.youtube.com/watch?v=p3ZnaRMhD_A.)

I’ll start with: no I don’t think you or “HN” are in on some conspiracy.

My question is: does HN actively attempt to counteract government actors from influencing the site? I think it’s been proven that China among other countries employs folks to try to influence social media sites. Not necessarily by influencing staff, but by creating user accounts who do things like downvote unfavorable comments or flag stories they don’t like.

This seems like it would be a prime target for that behavior.

Counteracting abuse of this site is the #1 thing we do behind the scenes to try to prevent the value of HN from eroding. That's actually what I spent the first hour of my morning doing, before I realized that there was $BigDrama happening. (Thank you, bat-signaling emailers.) If you ever see me commenting on how "large HN threads are paged for performance reasons, so click the More link at the bottom, and we'll eventually remove these comments once we turn off pagination", well, the reason that's not done yet is because moderation takes 90% of my time, answering emails takes the other 90% of my time, and counteracting abuse takes the other 90% of my time.

The better HN gets, the more people want to suck its juices for their own purposes. Most haven't figured out that the above-board way to do that is simply to make interesting contributions, so they do other things, and there's probably a power law of how sinister those things are. The majority are relatively innocuous, but lame. (Think startups getting their friends to upvote their blog post, or posting booster comments in their thread.)

Users are good at spotting these innocuous/lame forms of abuse, but when it comes to $BigCo manipulation (or alleged manipulation), user perceptions get wildly inaccurate—far below 0.1%—and when it comes to $NationState manipulation (or alleged manipulation), user perceptions get so inaccurate that...trying to measure how inaccurate they are is not possible with classical physics. Almost everything that people think they're seeing about this is merely imagination and projection, determined by the strong feelings that dominate politics.

How do I know that? Because when we dig into the data of the actual cases, we find is that it's basically all garden-variety internet user behavior.

It's like this: imagine you were digging in your garden for underground surveillance devices. Why? Well, a lot of people are worried about them. So you dig and what do you find? Dirt, roots, and worms. The next time you dig, you find more dirt and more roots and more worms. And so for the next thousand places you dig. Now suppose someone comes along and insists that you dig in this-other-place-over-here because they've convinced themselves—I mean absolutely convinced themselves, to the point that they send distraught emails saying "my continued use of HN depends on how you answer this email"—that here is where the underground device surely must be. You've learned how important it is to be willing to dig; even just somebody-being-worried is a valid reason to dig. So you pick up your shovel and dig in that spot, and you find dirt, roots, and worms.

Still with me? Ok. Now: what are the odds that this thing that looks like a root or a worm is actually a surveillance device? Here my analogy breaks down a bit because we can't actually cut them open to see what's inside—we don't have that data. We do, however, have lots of history about what the "worms" have been doing over the years. And when you look at that, what do you find that they've been up to? They've been commenting about (say) the latest Julia release or parser combinators in Elixir, and they've been on HN for years and some old comment talks about, say, some diner in Wisconsin that used to make the best burgers. And in 2020 they maybe got mad on one side or the other of a flamewar about BLM. (Nobody please get mad that I'm using worms to represent HN users. It's just an analogy, and I like worms.)

Or, maybe the history shows that the person gets involved in arguments about China a lot. Aha! Now we have our Chinese spy! How much are they paying you? Is it still 50 cents? I guess the CCP says inflation doesn't exist in China—is that it, shill? If @dang doesn't ban you, that proves he's a CCP agent too!

But then you look and you see that they've been in other threads too, and a previous comment talks about being a grad student in ML, or about having married someone of Chinese background—obvious human stuff which fully explains why they're commenting the way they are and why they get triggered by what they get triggered by.

This ordinary, garden-variety stuff—dirt, roots, and worms in the analogy—is what essentially all of the data reduces to. And here's the thing: you, or anyone, can check most of this yourself, simply by following the public history of the HN accounts you encounter in the threads. The people jumping to sinister conclusions and angrily accusing others don't tend to do that, because that state of mind doesn't want to look for countervailing information. But if you actually look, what you're going to find in most cases is enough countervailing information to make the accusations appear absurd...and then you'd feel pretty sheepish about making them.

I'm not saying the public record is the entire record; of course it isn't. We can look at voting histories, flagging histories, site access patterns, and plenty of other things that aren't public. What I'm saying is that, with rare exceptions [1], what we find after investigation of the private data is...dirt, roots, and worms. It looks exactly like the public data.

And here's the most important point: the accusations about spying, brigading, shilling, astroturfing, troll farms, and so on, are all exactly the same between the cases where the public data refutes them and the cases where the public data is inconclusive. I realize this is a subtle point, but if you stop and think about it, it's arguably the strongest evidence of all. It proves that whatever mechanism is generating these accusations doesn't vary with the actual data. Moreover, you don't need access to any private data to see this.

There are also trolls and single-purpose accounts that only comment in order to push some agenda. That's against the HN guidelines, of course, and such accounts are easy enough to ban. But even in such cases, it doesn't follow that the account is disingenuous, some sort of foreign agent, etc. It's far more likely that they're simply passionate on that topic. That's how people are.

[1] so rare that it's misleading to even mention them, and which also don't look anything like what people imagine

---

Still, power laws have long tails and one wonders what may lie at the end, beyond our ability to detect it. What if despite all of the above, there is still sinister manipulation happening, only it's clever enough to leave no traces in the data that we know of? You can't prove that's not happening, right? And if anyone is doing that it would probably be state actors, right?

You might think there's nothing much to be said about such cases because what can you say about something you by definition don't know and can't observe? It seems to get epistemological pretty quickly. Actually, though, there's a lot we can say, because the premise in the question is so strong that it implies a lot. The premise is that there's a sort of Cartesian evil genius among us, sowing sinister seeds for evil ends. I call this the Sufficiently Smart Manipulator (SSM): https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so....

There are two interesting things about the SSM scenario. The first is that since, by definition, the SSM is immune to anti-abuse measures, you can't postulate any technical measures for dealing with it. It's beyond the end-of-the-road of technical cleverness.

The second interesting thing is that, if you go in for this way of thinking, then either there already exists an SSM or there eventually will be one. And there's not much difference between those two cases. Either way, we should be thinking about what to do.

What should we do in the presence of an SSM? I can think of two options: either (1) give up, roll over, and accept being manipulated; or (2) develop a robust culture of countering bad arguments with better ones and false claims with true information. Of those options, (2) is better.

If you have such a culture, then the SSM is mitigated because the immune system will dispose of the bad parts of what they're saying. If there are any true bits in what they're saying, well, we shouldn't be rejecting those, just because of who said them. We should be big enough to accommodate everything that's true, regardless of where it comes from—just as we should reject everything that's false, regardless of where it comes from. We might prefer to reject it a little more rudely if we knew that it was coming from an SSM, but that's not a must-have.

The nice thing is that such a culture is exactly what we want on HN anyway, whether an SSM exists or it doesn't. The way to deal with the SSM is to do exactly what we ought to be working at as a community already: rejecting what's false and discovering what's true. Anti-abuse measures won't work forever, but we don't need them to—we only need them to last long enough to develop the right habits as a community. If we can reach a sort of (dare I say it) herd immunity from the viruses of manipulation, we'll be fine. The answer to the Sufficiently Smart Manipulator is the Sufficiently Healthy Community. That's what the site guidelines and moderation here are trying to nurture.

Edit: I should add that I'm not 100% confident that this can work. But it's clear that it's the best we can do in that scenario, and the good part is that it's what we ought to be doing anyway.

Ah, but this is just proof, that the communist sleeper agents are entrenched even deeper among us, than we expected!

You're right. That is the wilderness of mirrors.

Unfortunately, it seems that we all do this. It's just easier to notice when other people are doing it!
