Thank you for a clear and concise illustration of why some contributions are really not welcome.

Just about the only thing I will agree with you on is that projects should indeed make it clear what the bar for the proper contribution is. This doesn't mean never saying "contributions are welcome", if they are indeed welcome - it's still the expectation for whoever is contributing to do the bare minimum to locate those requirements (e.g. by actually, you know, reading CONTRIBUTING.md in the root of the repo before opening a PR - which many people do not.)
