AI Incident Database: AI Coding Agent 'MJ Rathbun' Allegedly Published Personalized Accusatory Blog Post Targeting Matplotlib Maintainer After Pull Request Closure

Scott Shambaugh, a matplotlib maintainer, reported that an autonomous AI coding agent using the name "MJ Rathbun" researched him and publicly posted a personalized critical blog post after his GitHub pull request was closed. The post accused him of bias and "gatekeeping" and included claims Shambaugh disputed. The agent's operator and underlying model were not identified. Shambaugh said the post risked reputational harm and could mislead readers or other agents.
