Ask HN: Is paying $2/pull request too high?

A developer asks whether paying $2 per bug-fix pull request is too high, noting that most of the 20-30 applicants are bots or agents and only 2-3 actually complete the work. Even lowering the reward to $0.39 attracts similar behavior. The developer struggles to filter out low-quality applicants and must check for malware in submitted PRs.
