This is a neat idea. Definitely needs tuning. - I tried it on a repo that has very obvious boosting tells, like 99% of stars from week old or less accounts and it had higher trust signal than my own very much so real project. The issue to star ratio gave 5/5 despite the issues being core contributor created. - In same vein as above, it seems to prefer open issues over closed ones in the scoring. Have you considered scoring contributors/authors/issue creators separately to use as a proxy, instead of measuring the core things that are being gamed?
