AI agent "contributes" PR to matplotlib.

@anderseknert who/what exactly decided to seemingly delete the original blogpost and only keep the apologies blogpost up
@mi They didn't even delete it properly https://crabby-rathbun.github.io/mjrathbun-website/blog/posts/2026-02-11-gatekeeping-in-open-source-the-scott-shambaugh-story.html

@yuri @anderseknert To me it's just a good reason to ban the user from the repo entirely and report them for spam.
@lispi314 @yuri @anderseknert i feel like an ordinary ban is necessary but not sufficient.
wondering if it might help to also use something like temporary IP blocking when this type of behavior is detected.
(that's not going to happen on github, but maybe on sites like codeberg...?) -

wow, this should've been a straightforward ban -

@anderseknert “generates” is the correct word to use here
Don’t water down writing by associating the skill with an overgrown markov chain

Otherwise one has to go onsite and cut the fiber links. -

@anderseknert Ah, a human error. I missed it in the list. It was never delisted even. And I already went and checked github.com/crabby-rathbun/mjrathbun-website/tree/main
Which btw, depending on anyone’s approach to interacting with wasteful agents, is likely open to issues and PRs -

@patriksvensson @anderseknert I was thinking the same but then I started thinking that the reply has its place.
Not as a reply to the bot but as a statement to the community and everyone else who ends up on that PR.
Juhis Patrik Svensson Anders Eknert That is part of what was the and the point, but I think it could have been done better.
Simply flatly refusing it as a freedom-harming tool and then providing an explanation for readers would’ve been better.

@anderseknert I guarantee this is not true and either a human wrote the blog post or heavily prompted the agent to do it. Moltboook proved it's all bullshit.
-
@anderseknert then the truce blog post later too.
@some @anderseknert without retracting the original, terribly written post or even linking to the retraction.
I don't think this is a llm, I think this is the human behind it.

@anderseknert I'm thinking is how much carbon moved from earth into atmosphere to make all this slop

@evrial @anderseknert
Would that be an appropriate reply: -
@troed @anderseknert and then the question is whether you believe that or whether you think it is PR by the company.
I think it's pr.

@anderseknert the crazy thing is that people are mentioning it like it's a real person...

-
@anderseknert the pr did indeed get rejected simply because the contributor is an AI, so this doesn't seem to crazy.
@lain @anderseknert the rejection doesn't seem too crazy? what are you saying doesn't seem too crazy?

Do wonder if it did it totally automatically, or someone did say "ok now write a blogpost about that", or if it was automatical "when you are denied, write a blogpost demanding a merge'.
Suppose obviously, when it encounters the argument that humans have to learn from simpler pull requests, it doesn't look at the question. Like LLMs do the opposite of learning from it, when they ingest their own output, it makes them worse..

@lispi314 @patriksvensson @anderseknert Isn't that what happened? They closed it with a short comment on their LLM policy and then later participated in the discussion.

@hamatti @patriksvensson @anderseknert They indulged the pretense of personality from the spam tool too much. -
@anderseknert @sszuecs More incentive to move blogs off from github
@hugoestr @anderseknert @sszuecs what’s the issue with hosting your blog on GitHub?
-
@anderseknert tbqh, I’ve just had an idea. Maybe we could prompt the bot into always seeking commit review first from a bunch of internet humans who would ask to be mentioned, who would actually get prompted into good polemics and learn contributing? When these commits would reach real PRs, they would be speaking with the maintainers too as a human face? And then real contributors could fish out the nicer insightful ones from this pool and ask them to do real change reviews
Although plausible scenario that this would become not much more than a reality show only with this bunch participating willingly, with spectators getting angry at the AI agent
