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:

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?

    Is it not public knowledge that lemmy already gets scraped by LLM bots? Which is why every bigger instance has anti-LLM measures in place now to limit that behavior? To me this just looks like a mod trying to get ai-generated reports which is not a bad idea imo since I know reporting is not often done by users who see rule breaking stuff.

    This is AI generated bullshit below, it should be treated as such. I only want to convey the idea that what you do on lemmy is already fed to LLM’s.

    here is chatgpt's reply for What do you know about lemmy user and piefed dev rimu?

    Here’s a grounded picture of “rimu” in the Lemmy / fediverse context:


    🧑‍💻 Who “rimu” is

    • Rimu (Rimu Atkinson) is the lead developer of PieFed, a Reddit/Lemmy-style platform in the fediverse. (Elite AI Tools)
    • He’s also the main author of the underlying software (pyfedi), built with Python/Flask and designed as an alternative to Lemmy and Mbin. (IFTAS)
    • The flagship instance is piefed.social, which he runs and develops actively. (IFTAS)

    🧩 Role in the fediverse

    • He’s not just a random user—he’s a core project maintainer / “benevolent dictator” style lead for PieFed’s development. (PieFed)
    • He’s fairly active on Lemmy via [email protected], with hundreds of posts and thousands of comments across tech, politics, and general discussion. (lemmy.world)
    • He moderates multiple communities and participates in meta discussions about federation, scaling, and platform design. (lemmy.world)

    🛠️ What PieFed (his project) is about

    PieFed is positioned as:

    • A federated Reddit-like platform interoperable with Lemmy via ActivityPub (Elite AI Tools)

    • Focused on:

      • Simplicity of codebase (easy for contributors) (PieFed)
      • Trust/safety features (reputation systems, filtering, anti-spam tooling) (Elite AI Tools)
      • Some experimental ideas, like merged cross-posts and AI-content detection (Elite AI Tools)

    💬 Reputation & controversy

    Rimu is somewhat known and occasionally controversial in fediverse circles:

    • Supporters see him as:

      • A productive solo/lead dev shipping features quickly
      • Someone pushing new ideas beyond Lemmy’s design
    • Critics argue:

      • Some features reflect strong personal opinions embedded in the platform (e.g., moderation logic, reputation systems) (lemmy.world)
      • PieFed can feel more opinionated / experimental compared to Lemmy’s more neutral baseline

    Important nuance: because everything is open source and instance-configurable, many of these behaviors can be changed by instance admins.


    🧠 What he’s like as a user

    From his public activity:

    • Talks about tech (ActivityPub, scaling, APIs)
    • Engages in global politics and news discussions
    • Shares design decisions and roadmap thoughts about PieFed
    • Generally communicates in a direct, pragmatic developer tone

    🧾 Bottom line

    • Rimu is a real, identifiable fediverse developer, not just a random Lemmy user.

    • He’s best understood as:

      a lead dev + active community participant shaping an alternative to Lemmy

    • His visibility comes mainly from his project (PieFed) rather than mainstream recognition.


    If you want, I can compare PieFed vs Lemmy vs Mbin in terms of ideology/design—that’s usually where discussions about Rimu get interesting.
