Trust signals as sparklines for Hacker News

It's a nice idea, but I have mostly stopped using/installing any software that is not open-source a long time ago. So, please open-source it, especially if you want users to truly trust it.

Even then, I would recommend anyone to install (small to mid) browser extensions by cloning and inspecting the source and just then loading it yourself - if you don't know: any browser extension can read input/password fields across all site(s) you gave it access to (yeah, it's crazy but unfortunately true).

This could become/converted to a userscript making it easy to inspect and more cross compatible. It's very easy these days.

To be fair, the .xpi is just a .zip file, and the JS isn't minimized.

I vibe-converted it to a userscript[1], but it doesn't work for me in qutebrowser because it depends on profile data fetched from `https://hn-trustspark.com/alltrust.json`, which seems to be periodically updated by the author, and qutebrowser has limited userscript support. :(

It could probably be worked around by fetching the data externally, but I don't want to depend on hn-trustspark.com. It would be great if the profile updating tool could be published as well.

Anyway, hope it helps someone else :)

FWIW, after a quick review of the script, it looks safe to me. As long as you trust that the served profile data is correct, and don't mind leaking your IP to it.

Great idea and kudos to the author! We need more tools like this to help us deal with spam, and not just on HN, but everywhere.

Thanks! Nice, you found the alltrust.json file ha. Yes, a bg job running on an rpi leverages HN APIs and builds the alltrust file by the minute, for all "active" accounts. Technically fetching that data is all you'd need to make your own script/plugin.

It's centralized for a few reasons though, first being that client-side API requests would be discourteous to the APIs (flood/ddos), and a whole new level of error handling would be required. Shared IPs, like those in a tech company building, would easily and quickly reach the API limits. So that's the reasoning, if you're curious.

It's a good idea, provided nothing sketchy goes on either now or in a future update ... I'm playing about with it but will likely unload it soon enough.

One issue: New accounts with Zero submissions get a full green stack for "Submission Trust" (0 submissions in 0 days).

That comes across as three flat red lines and a singl tall green stack - not sure if that's the right message.

Submissions is an odd one ... those people that submit a story seen on the tech blogs once a day get bucketed together with habitual spammers of poor quality posts.

Author here. This is a good callout, there are a few reasons why it's a plugin and not open source (yet).

First is that I didn't want to make a plugin in the first place, I wanted to make a bookmarklet, but HN's CSP policy was too strict. So that was a bummer.

Second is that I have very mixed feelings about open source these days, and so open-sourcing feels less and less like the sensible default state. One of the sibling comments here discovered the alltrust.json and vibecoded around it, which is really a case in point about why open sourcing feels like I'd be leaving myself "open" to be domineered (not just by users, but by bots and companies as well).

Third is that the system/plugin is partly LLM-assisted itself (even though the code is minuscule), and I'm self conscious of being a slop-slinger. Or at least, pushing up repos with LLM code just feels, idk... lazy and asymmetrical (despite this plugin having clear utility, which I think it does).

But it's completely fair to say "oh look, a plugin about trust that's closed source, how hypocritical." I get that. If there's enough interest I'll open source it, sure.

by solaire_oa

3/28/2026 at 7:18:30 PM

Hey, that's a perfectly reasonable stance, and I can relate to it.

Apologies for working around it and putting the code out there against your wishes. If you check my post history, you can see how opposed I am to these new tools, and "vibe coding" specifically. In my defense, I really didn't want to spend a lot of time on this, and LLMs do a decent job at this type of mechanical conversion. And I really don't judge anyone for using them mindfully, as you've clearly done in this case. The code didn't read like slop to me, if it's any consolation. :)

Besides, this "closed source" criticism is really a non-issue in this case considering it's a browser extension with clear JS, which anyone can inspect if they were really interested.

Cheers!

EDIT: I've deleted the gist. :)

by imiric

3/28/2026 at 8:24:48 PM

No problem at all! I didn't mean to be accusatory. And I wouldn't say inspecting the plugin code is against my wishes at all, no, definitely keep that hacker spirit alive! And feel free to reload the gist.

I suppose that my point is more that creating a GitHub repo has some strings attached to it nowadays, is all.

by solaire_oa

3/28/2026 at 11:16:17 PM

I've found many developers having switched to non-github forges (e.g. forgejo/gitlab/sourcehut or what have you), but particularly self-hosted instances, to sort of opt-out of the culture around mpdern-day open source. My sense is the barrier of entry is a social signal that they'd like to opt out of being assigned community manager+tech support+moderator for anonymous users. typically there isn't a functional issue here, but I guess avoiding the town square is a good way to avoid having to interact with the town drunk/crank/large language model

by qubidt

3/29/2026 at 8:38:28 AM

Appreciate the long reply and insights into your thoughts. I feel your resistance of slinging LLM slop, but hiding it doesn't make it better. I'd far more appreciate it being open source and mentioning it has been generated with LLM assistance, over not mentioning it at all. If the code has been reviewed and is simple enough to understand, it's appreciated and not perceived as vibe coded slop.

by mentalgear

3/29/2026 at 3:31:20 PM

For sure, source is now available here https://hn-trustspark.com/src/

I can figure out how to shasum/sig the extension for heightened trust.

by solaire_oa

3/28/2026 at 11:36:44 AM

Wow "trust as in trust me bro", thanks for the heads-up. Only Y Combinator is allowed that level of access to HN karma metadata right now; what a gold mine.

by password4321

Interesting idea, wondering if the 4 bars are a good way to evaluate accounts.

Some more thoughts:

1. The website needs a description of what this project even is.

2. Open-source the code, especially since it's just for the community, I'd be vary of installing "some random" extension from the store.

3. The modal element in the iFrame on the website is cutoff on mobile widths using Firefox.

Interesting, but how is the trust signal measured? I couldn’t find this information

by cpa

3/28/2026 at 8:51:41 AM

If it’s not transparent, it kind of defeats the whole idea of a “trust” signal — at that point it’s just a number you either believe or ignore.

"trust me bro" signal

by xnx

3/28/2026 at 8:12:27 AM

I'm pretty sure it's based off of the configuration in the green gear in the top right of the iframe. You can inspect the ways it's calculated from karma, comments, etc etc

by cobertos

3/28/2026 at 9:20:18 AM

If you look at the config it's based on karma, comments, submission rate, comment rate (optional), and account age (that is, if you trust it actually uses the config how it says)

by CalRobert

3/28/2026 at 10:37:11 AM

There are some high karma accounts which make a great contribution, and others which ... don't. I'm doubtful whether karma or account age has a significant signal beyond anti-spam.

But it would be useful to know if I had up/down voted them significantly in the past.

by angry_octet

3/28/2026 at 10:51:58 AM

The only thing karma reliably indicates is participation over time, the signal is too noisy for anything else. If anything high karma should be a red flag. The very best contributors here rarely comment because they have better things to do. It shows an 8/8 score for me and I doubt anyone would consider me a top tier high quality contributor.

A plugin like HN Comments Owl would be more useful IMHO.

by krapp

3/29/2026 at 8:32:23 AM

As if to demonstrate my point, two high karma accounts have down voted my suggestion that karma is meaningful. Naturally they are too craven to enter the field.

by angry_octet

3/28/2026 at 7:56:40 AM

Great idea.

I think friend/foe and trust signals should come from a user's voting. So I think it should operate transparently to the user and there should be a default shade-out option of bad actors, but with the option to view. So it's set-and-forget. On the backend - could you make it so if you've never visited HN before, and you install the plugin, the experience changes accordingly?

I had the idea to setup a forum somewhere else - this sort of functionality would come in handy as part of normal operation.

by adrianwaj

3/28/2026 at 8:33:42 AM

After attention, are we now in the trust economy… a brilliant idea for a plugin - thank you!

by vivid242

3/28/2026 at 9:37:22 AM

The problem is that I don't trust plugins.

Is there a way to do this from a bookmarklet?

by amelius

3/28/2026 at 3:37:06 PM

Author here. I tried a bookmarklet, that was my preference, but the security headers in HN were too strict. As far as I could tell anyway.

by solaire_oa

3/28/2026 at 1:47:31 PM

Site breaks for my account? Maybe I'm not trusted? But I see no sparklines next to my username when I visit https://hn-trustspark.com/ and have posts on the newest page.

by mooreds

3/28/2026 at 1:48:34 PM

Actually, it did just blur out one of my submissions so maybe it does work and my other submissions are, as the kids say, mid.

by mooreds

3/28/2026 at 4:12:20 PM

Oh wow, You're a human with a high submission rate! I assumed accounts like these were bots. I've seen a large number of accounts like yours in `/newest`, indeed, it's the reason I made the default demo penalize high submission rates. If you don't mind me asking, what are you submission habits? Do you just submit links you find interesting often? And does the karma rewards factor into your routine submissions?

(I'm not being facetious or accusatory, I'm genuinely interested learning how some of these high submission rates operate, since a lot look automated).

by solaire_oa

3/28/2026 at 5:37:49 PM

haha, no worries.

> what are you submission habits? Do you just submit links you find interesting often?

Pretty much. I will often email myself links I think might be interesting, then batch up submissions. I also like to highlight friends' posts.

> And does the karma rewards factor into your routine submissions?

It's always fun to get karma, but I like the fact I can call attention to someone or something that deserves it more.

I also wrote and talked about my thoughts on HN and how to be a good community member a bit more:

- in this blog post: https://www.mooreds.com/wordpress/archives/3530

- in this podcast: https://www.youtube.com/watch?v=VrObxK-J_3I

by mooreds

3/28/2026 at 8:01:45 PM

Darn, I really thought submission rates were the lowest hanging fruit for bot detection, and it doesn't appear this is the case.

Thanks for commenting so I could see this.

For what it's worth, penalizing submission rates is not the default in the plugin itself, that's just for the demo. And also, in my testing, HN at large has "high trust" practically everywhere. My own account is consistently one of the lowest scoring that I come across, ironically. So perhaps this plugin isn't as useful as I had hoped.

by solaire_oa

3/29/2026 at 12:29:09 PM

Hmmm. No data here, just heuristics from my time on HN, but if I were looking for bot accounts, I'd look for:

* a large percentage of posts from the same domain

* a large number of flagged posts

There are also some domains that show up when you are logged in and submit them and don't show up if you view the page anonymously (the entire domain has been added to the killfile). dev.to is one of these.

Submissions of those domains might be automated.

Good luck!

by mooreds

3/28/2026 at 9:21:26 AM

Suggestion: instead of just popping in the computed graphic add a placeholder immediately - four low grey bars should work well, in the same width as the final sparkline graphics. That way the text on the page will not jump later when the final sparklines are ready.

by onli

3/28/2026 at 9:38:13 AM

Great idea! I've been running my own chrome plugin I made that is similar, but recently discovered this: https://oj-hn.com/ and intend to start to contribute to it as it's very good and hope it grows. Something like Sparklines would be great in oj also for us chrome users, I really like the Sparklines implementation.

by alex7o

Install the plugin and then load up your profile page, or any page with ac omment from you (like this one)

You have an overall 7 out of 8.

This should have at least a basic description of how the trust signal works and is calculated

by Kkoala

3/28/2026 at 9:40:36 AM

I considered something like this but I find the UX of information too noisy. In practice, I much prefer simply performing a ternary block/leave alone/highlight functionality. And it's comments that bother me more than links.

by arjie

3/28/2026 at 11:45:53 AM

The problem with having a public trust score is that it'll be gamed by bad actors A/B testing their bots surely.

by Lapra

I wouldn’t call four bars a sparkline.
