> I have a simple rule: whenever I receive an issue or PR from an unfamiliar account, I skim the text and/or code and post 1-2 quick questions. If the submitter responds intelligently, then the issue warrants a more in-depth investigation. If not, the submitter clearly doesn't think that the issue is worth following up on, so it's not worth my time, either.

And if the submitter responds with "Great question! ...", what then? :D
