For quite a few years the Rails project has been working with the Internet Bug Bounty (IBB). The IBB is an organization that awarded cash to security researchers that reported issues to OSS projects participating in the IBB. For quite a while I wasn’t certain about my feelings toward the program because I felt like cash rewards could incentivize low quality reports as well as encourage reporters to “haggle” about the severity of a particular bug (the IBB paid more when the bug was more severe). In the beginning that certainly was the case. We were fielding many low quality reports, and people were haggling over severity. But the program evolved, and despite the never-ending haggling, I felt it did more good (rewarding security researchers) than bad (forcing the security team to wade through low quality reports).
