Feels like making a messaging app but "how messages are delivered and to whom is left to the user to implement".

I think "who and how someone is vouched" is like 99.99% of the problem and they haven't tried to solve it so it's hard to see how much value there is here. (And tbh I doubt you really can solve this problem in a way that doesn't suck.)

The real problem are reputation-farmers. They open hundreds of low-effort PRs on GitHub in the hope that some of them get merged. This will increase the reputation of their accounts, which they hope will help them stand out when applying for a job. So the solution would be for GitHub to implement a system to punish bad PRs. Here is my idea:

- The owner of a repo can close a PR either neutrally (e.g. an earnest but misguided effort was made), positively (a valuable contribution was made) or negatively (worthless slop)

- Depending on how the PR was closed the reputation rises or drops

- Reputation can only be raised or lowered when interacting with another repo

The last point should prevent brigading, I have to make contact with someone before he can judge me, and he can only judge me once per interaction. People could still farm reputation by making lots of quality PRs, but that's actually a good thing. The only bad way I can see this being gamed is if a bunch of buddies get together and merge each other's garbage PRs, but people can already do that sort of thing. Maybe the reputation should not be a total sum, but per project? Anyway, the idea is for there to be some negative consequences for people opening junk PRs.
