Project mention: We stopped AI bot spam in our GitHub repo using Git's –author flag | news.ycombinator.com | 2026-05-18
I have 3 PRs on https://github.com/django-oauth/django-oauth-toolkit/pulls that haven't been merged for OVER AN YEAR due to the maintaners being overloaded and who are expected to work on this for free. The fact that these PRs are not being promptly reviewed have cost me at least 3000€ in potential grant work.
If I was told that I would make a deposit of $100 just to get the PR reviewed, I wouldn't even blink.
