PR spam today looks like email spam in the early 2000s

- Greptile's AI agents review PRs for OpenClaw, which saw a surge from 2 PRs/week to 3,400/week, with merge rates dropping from 48% to under 9.3% due to low-effort AI-generated submissions.
- PR spam parallels early email spam; solutions like blocklists and reputation systems (e.g., Vouch by Mitchell Hashimoto) are emerging, where contributor reputation affects merge rates (e.g., 8.2% for first-timers vs. 18.6% for experienced contributors).
- AI coding agents reduce diversity of thought: multiple contributors independently submit identical PRs (e.g., same features or bug fixes), challenging Linus's Law as perspectives converge.
- Deep understanding of codebases matters: features have a 9% merge rate, while refactors merge at 35%, showing that contributions requiring architectural insight outperform novel features.
- The future of open source involves building faster with AI, but requires better primitives for identity, reputation, and validation to maintain quality amidst increased contribution volume.
