MODERATORS
 

I recently discovered that some popular federated instances have been using LLM-assisted moderation tooling that evaluates whether someone has said something bannable. They do this by running a script/app that sends the user’s comment history to OpenAI with the question “analyze this content for evidence of specific political ideology sentiment. Also identify any related political ideology tropes“. (The italic bits are where I've redacted the ideology they're seeking).

OpenAI’s LLM (they’re using GPT-5.3-mini) then responds with something like:

image

and so on, hundreds of comments.

I have not named the instances or people involved, to give them time to consider the results of this discussion, make any corrective changes they want and disclose their practices at their own pace and in their own way. I have also redacted the evidence to avoid personal attacks and dogpiling. Let’s focus on the system, not the individuals involved. Today these instances and people are using it and maybe we’re ok with that because it’s being used by groups we agree with but what if people we strongly disagree with used it on their instances tomorrow?

The use and existence of this tooling raises a lot of other questions too.

What are the risks? Fedi moderators are often unsupervised, untrained volunteers and these are powerful tools.

What safeguards do we need?

Would asking a LLM “please evaluate this person’s political opinions” give different results than “find evidence we can use to ban them” (as used in the cases I’ve seen)?

What are our transparency expectations?

Is this acceptable and normal?

Should this tooling be disclosed? (it was not – should it have been?)

If you were given a choice, would you have opted out of it?

Can we opt out?

Are there GDPR implications? Privacy implications? Should these tools be described in a privacy policy?

Are private messages being scanned and sent to OpenAI?

How long should these assessments be retained and can we request to see it, or ask for it to be deleted?

Once the user’s comments are sent to OpenAI, is it used to train their models?

What will the effect be on our discourse and culture if people know they are being politically profiled?

Where are the lines between normal moderation assistance tools, political profiling and opaque 3rd-party data processing?

I hope that by chewing over these questions we can begin to establish some norms and expectations around this technology. The fediverse doesn’t have any centralized enforcement so we need discussions like this to develop an awareness of what people want in terms of disclosure, privacy, consent and acceptable use. Then people can make choices about which instances they join and which ones they interact with remotely.

And of course there are the other issues with LLMs relating to environmental sustainability, erosion of worker’s rights, increasing the cost of living and on and on. I can’t see PieFed adding any functionality like this anytime soon. But it’s happening out there anyway so now we need to talk about it.

What do you make of this?

I don't doubt it even for a second.

I'm lowkey kind of fascinated this morning with what feels like a moment of real panic among western liberal-democratic institutions (projecting a little from my morning news and coffee). That an anarchist instance is getting this much targeted harassment feels like a microscopic extension of that (if I allow myself to be so bold)

As far as I can tell, dbzer0 isnt even being explicitly called out here, but it has an undeniable bdzer0 flavor to it. If it doesnt come out that this was one of our mods at this point, I'd almost be disappointed.

[–] Stamets@lemmy.dbzer0.com 13 points 14 hours ago* (last edited 12 hours ago) (2 children)

Yep and it doesn't help that Rimu himself is a very questionable dude. He says he defederated from lemy.lol over their pepe frog logo but honestly I don't believe it is the reason/ He hates memes. He said as much to me himself. A while back, someone realized that piefed was hard coded to give negative reputation to certain people, regardless of what settings the admins had made. Piefed is built off of Rimu's opinions and he puts the majority there as an opt-out, not an opt-in. When I made a jokingly apology for all the memes I post, he said "It's not your fault that the lemmy devs didn't put guardrails in."

If he's that opinionated about memes...

Combine that with the fact that this post has literally no information other than "Trust me bro"? I don't trust Rimu as far as I can throw his garbage platform and I can't even throw the thing because its digital code. Hell, Mr. Kaplan even had to do a ton of un-fucking of Piefed to get piefed.world to work and was talking with me about it at the time. Just LITTERED with Rimu's stances.

Not to mention that Rimu routinely comes in with preconcieved notions that others have to point out the bullshit of and he quietly then steps back from it or refuses to engage entirely and dismisses it out of hand.

Like... the Lemmy devs suck, absolutely. But the only facet in which Rimu is better is he's not a transphobe.

Edit: See below for screenshots. I'm tired of this shit. Yes. He's wildly opinionated.

Please don't spread old mis-info or at least back this up with actual links to the source-code (and if we are talking about the same thing, this was clearly debunked).

As for the OP post, this is factually correct and I have seen the evidence. Although maybe Rimu should have been more clear in pointing out that this seems to be not an official instance tool, but rather something some moderators have cobbled together themselves.

[–] Stamets@lemmy.dbzer0.com 11 points 13 hours ago* (last edited 12 hours ago) (2 children)

Please don't spread old mis-info

I mean, you just did it. The OP post is not factually correct as he stated that it is at an instance level. It is not. It is at a moderator level.

Please don’t spread old mis-info or at least back this up with actual links to the source-code (and if we are talking about the same thing, this was clearly debunked).

Gotta say though, getting real tired of people telling me that I didn't understand conversations I was a part of. No. It was not 'debunked'. It was added under an opt-in toggle after everyone noticed it and called out his bullshit. You might be thinking of something else, but this is what I was talking about.

Piefed is infected with Rimu's extreme opinionated garbage and he only backs down and puts them into a toggle after someone notices it. That's not the behavior of a developer that I find personally trustworthy. So when he's out here making a post that is outright false, claiming that instances are doing something that moderators are doing, I don't trust him. Not to mention the extremely long conversations I had with Mr Kaplan about how Piefed.world needed to be un-rimu'd in order to work as LW wanted it to.

Piefed is infected with Rimu’s extreme opinionated garbage and he only backs down and puts them into a toggle after someone notices it.

I personally prefer Rimu taking feedback into account and then making changes than Lemmy devs bluntly closing feature requests widely upvoted by the community because "reasons"

Let's be honest here, it's not like there are so many options we can choose from.

Also, the example you gave about shows more than anything else that Rimu did change his mind.

"All the settings in this screenshot are off by default"

[–] Stamets@lemmy.dbzer0.com 5 points 7 hours ago (2 children)

He only changed his mind after someone discovered it. The thing I don't like is his obfuscating his opinions that he's injected into Lemmy. Having to manually discover them and then bug him about adding an opt out toggle is not exactly trustworthy behavior nor is it something I'm going to applaud. He still tried to sneak it in regardless and only backed down when called out. I'm not giving him props for that.

[–] eugenevdebs@lemmy.dbzer0.com 5 points 6 hours ago (1 children)

Rimu is like Microsoft Windows.

Adds in things the higher ups felt was needed. Users then discover it and say this is a bad thing to include in software.

Microsoft then says "right our bad, we should have thought twice on this"

Microsoft then does it again a few weeks later, repeat.

[–] Blaze@piefed.zip -3 points 6 hours ago

Comparing a single open source developer to one of the biggest tech corporations worldwide doesn't really seem relevant.

Adds in things the higher ups felt was needed.

Who are the higher ups in this case? There's no Piefed board of management or investors to answer to.

All of that being said, I'm looking forward the day Pievolution can be run easily, then every instance can make their own choices, and these endless debates will end.

[–] Blaze@piefed.zip -3 points 6 hours ago (1 children)

The code is open source, nobody bothers to read it. If that's supposed to be obfuscation, then that's not really effective.

[–] Stamets@lemmy.dbzer0.com 3 points 4 hours ago

The same arguments are made when an overwhelming amount of paperwork is dumped on someone during discovery in a trial. It's not a good argument then and it's not a good argument now. If you have to go through and check every single thing he's done to find the hidden things he's put in there without announcing then that is not transparent. You simply cannot change the fact that Rimu overwhelmingly puts his opinions into Piefed as a whole and then leaves it for everyone else to find the opinion and then tell him to add a toggle. He fights against it before eventually adding a toggle. Meanwhile, damage has already been done for however long with his garbage running rampant without anyone noticing it.

If he is not willing to point out what is opinion and what is code then I am not willing to fact-check every piece of his work to find what is code and what is crap. He's being disingenous and underhanded.

I am not continuing this conversation.

[–] poVoq@slrpnk.net -3 points 11 hours ago (1 children)

I was referring to a different but similar case where someone intentionally spread mis-information about supposedly hardcoded things that turned out to be a complete nothingburger as all of it was behind an admin toggle. The same seems to be now true for this old issue you specifically pointed out here.

It is true that there is some experimental stuff in Piefed, which is part of the relatively rapid iteration of features, but looking at the code and also the explanations given by the Piefed development team I can really not see any malice in those settings. It is perfectly normal that things get overlooked or implemented partially and when someone reports a bug (like a missing admin configuration setting) it usually gets fixed quite quickly, and at least in my experience without much discussions.

[–] Stamets@lemmy.dbzer0.com 8 points 10 hours ago* (last edited 10 hours ago) (1 children)

The same seems to be now true for this old issue you specifically pointed out here.

But it isn't. First off, you made an assumption and dismissed my initial complaint. Now you're dismissing this one saying it's basically the same thing when it isn't. Having a long discussion with large admins saying "Hey. What the fuck is this stuff?" only for Rimu to constantly push back and saying how he wants to reshape everything is fucking concerning. The fact it took everyone pushing back against him to add it under a toggle even more so. You'd have a point with the whole "this happens" if this didn't happen with every single major Rimu feature.

But, once again, Rimu is actively pushing misinformation and you have dodged the point that you are doing the same. This is not an admin or instance level problem. Moderators are doing this and claiming this is "instance level" is to be a liar.

It is perfectly normal that things get overlooked or implemented partially and when someone reports a bug (like a missing admin configuration setting) it usually gets fixed quite quickly, and at least in my experience without much discussions.

And, as we all know, your experience is the only universal experience that everyone has at all times. I guess the month long conversation I had with Kaplan, head admin of Lemmy.world, about unfucking Piefed because Rimu filled it with his opinionated garbage didn't happen. I guess the fork of Piefed being created that's taking out all of his opinionated garbage didn't happen. Not to mention his 4chan screenshot scanner (that can be bypassed immediately), the cm0002 filter he put onto piefed.social (that can be bypassed immediately), the blocking of any numbers of 88 put together (which can be bypassed immediately), the private votes that would prevent admins from locating vote brigaders (which can be opted, granted, but after a HEATED discussion in the piefed matrix).

Rimu is over opinionated to a fault and Piefed is the same.

You know nothing of which you speak.

But, once again, the only important point is that Rimu is actively spreading misinformation by claiming this is an instance problem when it is moderators that is doing it. Once again, with action after action, Rimu cannot be trusted.

[–] Blaze@piefed.zip -4 points 8 hours ago (1 children)

I guess the month long conversation I had with Kaplan, head admin of Lemmy.world, about unfucking Piefed because Rimu filled it with his opinionated garbage didn’t happen.

So Kaplan knew about the "garbage", but still wanted to go on and keep running Piefed.world?

Either Kaplan's judgement is supposed to be relied on, or not, but that argument seems weird to say the least.

which can be opted, granted, but after a HEATED discussion in the piefed matrix

So it is opted. That people have to convince Rimu to make changes isn't really an argument. People have to also convince the Lemmy devs to make changes on a regular basis, with less success.

[–] Stamets@lemmy.dbzer0.com 7 points 6 hours ago (1 children)

Either Kaplan’s judgement is supposed to be relied on, or not, but that argument seems weird to say the least.

Others are doing the same thing. This isn't "weird" or bad judgment. I don't like Kaplan but they did nothing wrong here.

So it is opted. That people have to convince Rimu to make changes isn’t really an argument.

Yes. If you skip over the entire problem, it does appear as if there is no problem. My issue is that he had to have his feet held to the fire over something that minor because he did not disclose it in the first place. If someone keeps trying to sneak shit past my face and then keeps backing down and going "Uwu sorry I add opt out" but then doesn't add opt out for the other opinionated stuff that was not discovered yet, why would I applaud them? They're still doing the bad thing.

[–] Blaze@piefed.zip -1 points 6 hours ago (1 children)

Others are doing the same thing. This isn’t “weird” or bad judgment. I don’t like Kaplan but they did nothing wrong here.

What I'm saying is that even though admins know there were some opinions in the software, they still started Piefed instances. And that's in a world where Lemmy exists.

In other words, every instance admins assesses whether the additional Piefed features make it worth it to accept the opinionated aspect of the software.

That's the main value of Piefed here, and that's why so many people prefer it compared to Lemmy. All the features people wanted, be it users, mods, admins, Rimu delivered them, and fast.

They’re still doing the bad thing.

Doing something, even imperfectly, but listening to the users, still seem valuable to a lot of people. Some people obviously dislike it a lot, and expect the software to be written be a perfect person, but the devs behind Lemmy, Piefed and Mbin all have their flaws.

I did not state whether or not Piefed.world was created before or after it was found out that Piefed is littered with Rimu opinions. You are making a conclusion you simply cannot make.

He said, off of a false conclusion from a random assumption.

Brother, you are not listening to a word I have been fucking saying.

He's not doing it imperfectly. HE'S BEING DISINGENOUS. If I were to talk to you and give you a ton of shit, fill all of it with some useful stuff but the rest is hyper opinionated, you'd expect me to tell you what was opinion and what isn't. Rimu doesn't. People have to discover it and then hold his fire to the flame. That is not listening to feedback over things that you knew was a problem. Especially when he knows it is opinionated and then puts it through anyway without informing anyone, without making a note of it, and expecting others to comb through his garbage and hold him accountable. And you are saying that is perfectly acceptable behavior?

Brother, you have lost essentially all of my respect here. As stated elsewhere, because you started two conversations with me at once, I am not continuing this with you.

Although maybe Rimu should have been more clear in pointing out that this seems to be not an official instance tool, but rather something some moderators have cobbled together themselves.

This isn't an issue of clarity. His closing call to action is to 'develop awareness so that people can choose which instances to join and interact with'. There aren't any practical administrative solutions to the problem being called out, with the exception of defederation or the threat thereof. Any single user on the entire fediverse can copy-paste user activity into any LLM and use the output to make moderation decisions, or craft personalized agitprop or whatever else, but centering the focus on instances that allow their usage turns the issue into a nail that can be solved with a hammer.

[–] poVoq@slrpnk.net -3 points 11 hours ago (1 children)

You are jumping to conclusions. I think it is generally worthwhile to discuss the use of LLMs for making moderation decisions and also using them to produce ideological profiles of users.

[–] anarchiddy@lemmy.dbzer0.com 7 points 11 hours ago* (last edited 10 hours ago)

The worthiness of a discussion has no bearing on the intent and framing of the person prompting it.

The questions are being raised by the same person who included global reputation scores in his backend piefed code for the purposes of suppressing his personal pet peve behaviors. I find that to be informative context for considering the intent of the discussion being prompted.

edit: Oh look, here he is saying exactly what I was just pointing out was likely the intent

[–] HubertManne@piefed.social 2 points 13 hours ago (2 children)

whats funny is I don't have much negative dbzer0 experience until you two guys start making this about that.

[–] ZombiFrancis@sh.itjust.works 6 points 12 hours ago

That's an odd takeaway, for sure.

[–] anarchiddy@lemmy.dbzer0.com 4 points 13 hours ago (1 children)

Is this a negative db0 experience for you?

[–] HubertManne@piefed.social 3 points 12 hours ago (2 children)

im just saying when there is a particular thing and someone starts pulling in something unrelated as a conspiracy it leaves a bad taste. Its a bit like folks suddenly saying something about lemmy.ml being so and so in an unrelated type post that gets me to do my posting in their communities but in a reverse kinda way. rimus last post about a trend he saw I think it had some interesting perspectives and few if any where that the instances were ban happy. Similarly this one has some good conversations going.

[–] Grainne@lemmy.dbzer0.com 1 points 2 hours ago

Rimu has confirmed this is about db0.

[–] ZombiFrancis@sh.itjust.works 3 points 12 hours ago (1 children)

unrelated

Well, it is noting that there's now at least an appearance of a relationship going on. Especially so, if you're already clued into the 'ban-happy' statistics magic thread.

Similarly this one has some good conversations going.

Hopefully those continue unimpeded and this can remain contextual or tangental.

[–] HubertManne@piefed.social 2 points 12 hours ago (1 children)

this one did not name any instances. paranoia is the only reason to link them or knowldge that the two things are indeed connected. Each is fine to me though. Bringing up data and slicing and dicing it a bit is fine and the convo brought up issues with the way it was massaged. Similarly this is about a particular thing. Niether indicated an opinion or want for some sort of action against instances. so yeah. unrelated. but yeah I like good and vibrant convo which is why I have enjoyed both posts. one thing im not wild about this is some comments suggest its an admin thing and should be discussed in some admin community but im not wild about the cigar filled room type thing.

[–] Grainne@lemmy.dbzer0.com 1 points 2 hours ago* (last edited 2 hours ago)

Statistics are what racists use to justify hate of minorities. Statistics are very easy to abuse and misuse, Rimu has used them to push a narrative when the reality is db0 was only high because of 1 moderator issuing a lot of bans which he used to frame an entire instance as ban happy.

These type of posts are why people (from all walks of life) view western leftism as more of an aesthetic, performative thing.

[–] Grainne@lemmy.dbzer0.com 1 points 2 hours ago

So right wingers complaining about leftists is why people view western leftism as performative?

Honestly sounds like maybe people should be taking issue with the complaining right wingers there.

[–] anarchiddy@lemmy.dbzer0.com 5 points 11 hours ago (1 children)

Right - which is why it was quite interesting watching Fox news have a 20 minute power struggle over the sudden popularity of May Day in the US and the rise of ""extreme socialist sentiment""

All online political discourse is performance - feel free to speculate how well it is representative of IRL leftist spaces in the west.

[–] Rekall_Incorporated@piefed.social 0 points 10 hours ago (2 children)

From my time in the US, what you describe seems like a pretty run of the mill local rhetorical strategy; a tried and true American polemic if you will.

Sure, but even with something like online political discourse you can do better than getting obsessed over a bastardized provincial political term (liberal which means something completely different outside of the US) and providing cover for promoters of russian and Chinese genocidal imperialism and propaganda. We are not talking about a deep discussion on philosophy and political economy, just the absolute basics.

Can't speak for your definition of leftist spaces, but many (not all of course) self-proclaimed western leftists IRL have a very performative approach to imperialism (among other things).

[–] Grainne@lemmy.dbzer0.com 1 points 2 hours ago* (last edited 2 hours ago)

liberal which means something completely different outside of the US

Not really, both imply right wing pro-capitalist beliefs. American Liberals just tack 'progressivism' onto their meaning to steal some left clout.

Sorry, I'm having a hard time following the train of thought - are you referring to my use of 'liberal-democratic institutions'?

I don't want to word-vomit on you unnecessarily if you're pointing to something else or speaking broadly about leftist discourse on lemmy (i've seen plenty of debates like the one you're describing)

and providing cover for promoters of russian and Chinese genocidal imperialism and propaganda

Ok well now i'm even more confused - where is this jab coming from?

Maybe you're taking issue with my categorizing db0 as a leftist space and are speaking broadly about the perspectives about china and russia from that instance? What are we talking about here?
