tl;dr: After OpenClaw went viral, weekly PRs jumped from 2 to 3,400 while merge rates collapsed from 48% to 9.3%, with much of the influx being AI-generated slop (one user submitted 106 PRs in a day). The author argues this mirrors early-2000s email spam and will require sender-reputation systems like Mitchell Hashimoto's Vouch, and notes that AI homogenizes contributions—multiple users independently submitted identical PRs. Refactors that require deep codebase understanding merge at 35% vs. 9% for features, suggesting human judgment still beats agent-generated novelty.
