Thanks, I wholeheartedly agree. It sucks to get a PR that was clearly work that you want to reject because it's a direction you didn't want to go, has big flaws, or would be hard to maintain.

I'm mostly talking about simple PRs, little bug fixes, even documentation improvements.

But even big PRs, all I ask is basic human courtesy that we provide each other in meat space. It's totally fine to say, "Thanks but I'm sorry we won't accept this." especially when it's out of the blue. What isn't fine is being rude. It's wrecking the community.
