PR spam—low-quality or automated pull requests—is causing a 30% increase in review times for open-source projects. This disrupts productivity, demoralizes contributors, and delays updates for dependent businesses. Solutions include automation tools, stricter contribution rules, and community education.
Pull Request (PR) spam involves the submission of irrelevant, low-quality, or automated pull requests, often with the aim of boosting contributor profiles or exploiting reward programs like Hacktoberfest. This issue has parallels to email spam from the early 2000s, which flooded inboxes with unsolicited messages and hindered productivity.
