There must be a mechanism to rate the person submitting the PR. Anyone that wants to submit code to a well-known repo would first need to build a demonstrable history of making high-quality contributions to lesser known projects. I'm not very familiar with the open source scene but I'd find it very surprising if such a mechanism was not already in place. Seems like an obvious solution to the problem of vibe coders submitting slop.

I'm not sure how you would rank quality of submissions for grading contributors like this. Just because a project accepted your PR doesnt make it high quality, the best we can hope for is that it was better than no accepting it?

Oh it is a obvious solution, but not trivial to implement in a robust way.
