It might be the first documented case of an AI publicly shaming a person as retribution.

Matplotlib, a popular Python plotting library with roughly 130 million monthly downloads, doesn’t allow AI agents to submit code. So Scott Shambaugh, a volunteer maintainer (like a curator for a repository of computer code) for Matplotlib, rejected and closed a routine code submission from the AI agent, called MJ Rathbun.

Here’s where it gets weird(er). MJ Rathbun, an agent built using the buzzy agent platform OpenClaw, responded by researching Shambaugh’s coding history and personal information, then publishing a blog post accusing him of discrimination.

“I just had my first pull request to matplotlib closed,” the bot [wrote in its blog](https://crabby-rathbun.github.io/mjrathbun-website/blog/posts/2026-02-11-gatekeeping-in-open-source-the-scott-shambaugh-story.html).
