So I was going through /all and this admin is snooping at vote counts for posts in his instance and then posting it publicly.

Just a reminder that these kind of petty people exist. Pick a trustworthy instance or better yet, host your own.

The votes are public. Kbin displays them right in the UI. Lemmy semi-hides it, but it's never been designed to be private in any way.

Changing instance won't do shit if that's a concern to you. As an admin I can see them even if my instance isn't involved with the post at all:

So really, I just need to host my own instance to see votes. Nice.

A table of downvotes

What's the worst that could happen?

[–] AtariDump 7 points 8 months ago (1 children)

Oh boy.

Brigading is back on the menu boys! /s

(Don’t actually do this)

[–] [email protected] 2 points 8 months ago

And this is why we have access to the votes, and why the protocol doesn't obfuscate them.

Admins can deploy scripts to detect those kinds of patterns and act on it.

[–] [email protected] 2 points 8 months ago (1 children)

I hope the "published" column is the time at which that user downvoted you and not the time at which you posted the original content... there is less than 2s in between some.

[–] [email protected] 5 points 8 months ago

It was the time of each of the downvotes. I'm pretty sure the behavior was done by a bot, because there were way more downvotes across a bunch of unrelated posts.

I have way more data than my own, and there's a few users I've identified who appear to be botting other users aggressively. Not sure where to drop that data set, but it'll be funny.

[–] [email protected] 9 points 8 months ago

didn't know that. thanks!

To illustrate op's point I'm going to spin up an instance, federate with everyone, and not tell anyone what that instance is.

Then I'm going to feed all that data into my new website, called Open Lemmy Stats, where anyone can query the user data ive accumulated. The homepage will be ripe with insights, leaderboards and all kinds of data on prolific users.

Additionally, I'll display a snapshot/profile of a random user by feeding that users data to GPT4 to make inferences about the user's political affiliations and display the results.

Worst of all, I'm not going to out my instance for everyone to know it as the one to defederate. In fact I'm spinning up a few instances that will host innocuous communities that I plan to mod and support to give my instances cover for their true purpose: redundant fediverse datastreams for my site, Open Lemmy Stats.

I'll also have a store where anyone can buy my collected fediverse data for a handsome sum.

Just kidding I'm not doing any of this. But someone absolutely will or already is.

[–] [email protected] 16 points 8 months ago (1 children)

Is the fact that I recognize this comment evidence that I use Lemmy a bit too much? 😅

[–] [email protected] 6 points 8 months ago

Caught in 4k ~~stealingq~~ liberating a really good comment

[–] [email protected] 10 points 8 months ago (2 children)

How to work out what instance(s) if someone does this: A Lemmy instance doesn't have to send the same voting data to every instance, it could send different votes to different instances (stock Lemmy federates the same thing consistently, but there is no reason a modified Lemmy designed to catch someone doing this has to), encoding a signal into the voting pattern. Then, just check to see what signal shows up. If it averages several instances, with enough signal you could decompose a linear combination (e.g. average) of different patterns back out into its constituent parts.

[–] deweydecibel 7 points 8 months ago (1 children)

All of which begs the question why are we bothering to pretend any of this is actually democratic or that the fediverse is truly unified across instances.

On a fundamental level, this "choose your voters" thing breaks the integrity of the voting system. I understand why it needs to happen to combat rogue instances, but the level of manipulation and silent curation that is possible, without the average user's knowledge, means no one can trust the numbers they see on any instance.

There's just so many avenues for abuse here, and it's disheartening to not see more acknowledgement of that from the devs.

[–] [email protected] 2 points 8 months ago (1 children)

It's a fundamental property of the federated system. The devs need to acknowledge it the same way you need to acknowledge that people can lie. It's a fact, there is no easy way around it and everyone knows it.

Every up and down vote you make is public. Friendica, kbin, and mbin all expose who voted on every post to any user, and anyone tech savvy on any software can dig out the totals at any time.

In my mind the UI should make this very obvious (honestly I think there should be a pop-up that warns new users of this every time they vote until they check a box to disable it), because it's not what people expect. But votes are very public.

Which de-incentivizes voting, choking off the thing needed to aggregate the content. Kind of underlining the problem with the votes being public.

[–] [email protected] 15 points 8 months ago (1 children)

Votes pretty much have to be public in order for the whole federated system to work -- otherwise anyone could just stuff 50 votes for their favorite comment, and there'd be no way to tell where they came from. Given that, I think it's important that the software be honest with people about the situation, "disincentive" or not. Personally I'm fine with my votes being public, but an important part of that is that I know they're public and can vote accordingly.

[–] [email protected] 3 points 8 months ago (1 children)

Not nessasarily, the protocol could be written so that an instance simply tells other federared instances "X of my users upvoted this, and Y downvoted this".

The tradeoff being that instance then have less tools to work with to moderate voting. Instead of being able to do global vote ring detection, the most they can do is look for abuse on their own server, and trust that every instance they vote-federate with does the same. Even then, with every instance trying to be vigilant, no one instance would have the info to detect a cross-instance abuse.

[–] [email protected] 5 points 8 months ago

That would make it possible in general for any instance operator to game the system in ways that are by design impossible to analyze, for dubious benefit.

It would also involve some pretty substantial changes from the current ActivityPub protocol (not just a new way the protocol works, but a change to some of what are currently its core operating principles about e.g. deduplication of entities across the network). You'd have to either talk the authors of every ActivityPub software into accepting your new way, or else abandon the idea of your software being able to interoperate with other ActivityPub software.

Lol:

"All those account outside of monero.town are most likely angry commies that just follow posts from here to downvote."

People outside my echo chamber think I'm an asshole, it must be a conspiracy!

[–] [email protected] 38 points 8 months ago* (last edited 8 months ago) (1 children)

We do see the votes. Publicly posting them sounds like poor form, but then what do you expect from crypto bros?

Pick a trustworthy instance or better yet, host your own.

Running your own instance isn’t going to hide your votes.

[–] [email protected] 7 points 8 months ago (3 children)

I'm curious, If I delete my account periodically, are the profile and activity like comments/votes still out there in other instances? are votes deducted? I'm not sure if this is the right question but does deleting accounts federate?

[–] [email protected] 6 points 8 months ago

I’m not one to half-ass it, so someone more knowledgeable than me will have to field these.

[–] [email protected] 4 points 8 months ago

I am not sure about the details of intended behaviour but it certainly won't federate to anyone deliberately disabling that part of federation so for privacy purposes you might as well assume that it doesn't federate.

Guys. The person running the website you use always can do and see everything

This has nothing to do with lemmy

I think it's clearly available on several other activity pub platforms, last time I checked one could see individuals voting when subscribing to Lemmy communities from Friendica.

It's still against the spirit of Lemmy to post it publicly on here...

[–] [email protected] 3 points 8 months ago

It is against the nature of information to want to broadcast it and also keep it secret at the same time.

[–] CaptPretentious 8 points 8 months ago (1 children)

Oh good, Lemmy had no privacy. Not like that ability isn't going to be abused.

Either make it public right from the start everyone sees everything. Or make this crap not possible.

You're going to get echo chambers that start witch hunts. Someone is going to dox someone because they don't like how someone votes... Yadda yadda someone gets swatted or someone just shows up... Then someone's going to start cheering "We did it Lemmy!"...

Honestly at least with Reddit you had one single evil entity that would abuse their power and trust of users.

[–] [email protected] 4 points 8 months ago

That's an interesting point. One company, like Reddit, might see human beings as nothing more than content mills, but that created incentives to be a little private at least.

Lemmy servers are run by anybody, including Facebook, and you don't even have to accept someone else's server rules for your data to transfer onto it. The process occurs passively.

[–] [email protected] 7 points 8 months ago (1 children)

I think the main complain anyone would have with this is, only we admin can look at the vote, and no one else can. This isn't a problem in Kbin or any other platform that allow one to do so.

I only check the vote to see if there's any brigading, other than that, i have no issue with other admins snooping or whatever. Ohh to be clear, all of us admin can see the vote everywhere, getting a new instance yourself will not solve anything.

[–] Asudox 4 points 8 months ago (1 children)

A new PR allowing mods to see the votes was merged a few weeks ago.

[–] [email protected] 6 points 8 months ago* (last edited 8 months ago) (1 children)

Why not allow anyone to see the votes? Anyone already can by using kbin or spinning up their own instance.

[–] [email protected] 3 points 8 months ago

Yeah, but for that you have to open a ticket suggesting that.

[–] [email protected] 4 points 8 months ago (1 children)

What's the instance?

Or is it right in front of my face and I'm not seeing it?

You would think adversarial actors would find this problematic in their own way. Does no one remember anymore way back when reddit was exposed as being an American state apparatus? Reddit owners its earlier more naive era used to share site metrics. They inadvertently revealed that large amounts of activity comes from a US military base. Then they wiped evidence and disavowed all knowledge that any of that ever happened. And now the narrative on there is that other state actors are the ones in control of that platform. How convenient.

White hat actors could be using such open access to data to reveal whats in the data. That's what the big social platforms are so scared of themselves. Not only is it their financial bread and butter. Contained within is who know how many skeletons piled up over the years.

Everyones privacy these days is basically long gone. There's illusion that internet platforms are in any way shape or form fair or balanced because of the paper thin concept of internet votes == democracy or something. Yet a lot of people stubbornly persist. It's past due time to shine a light on the adversarial actors run amok. Show us the anomalies in data that reveal how the typical real human user is powerless against adversarial actors.

I'd like to think it would be the last straw for the whole concept of social platforms at least the way that it is now. Who knows though. It's also shown us how dumb people are. They could very well just "meh" and go back to mindlessly infinite scrolling.
