This already exists, downvoted and closed questions will usually be removed automatically. The exact criteria are listed in this post on Meta Stack Exchange: Just to formally document the exact policies we have in place to remove old abandoned / dead questions, the Community user will delete questions in the following circumstances: If the ...

I support Darij completely. I'll even go a bit further and say that any thread that stood open since 2009 until 2019 without any complaints or controversies is good enough to stand forever and I'd rather risk offending a few good people than letting the "social justice warriors" control the discussions in any way beyond politely voicing their suggestions now ...

They got selected for deletion because of lack of community interest: If the question is more than 365 days old, and ... has a score of 0, or a score of 1 in case of deleted owner has no answers is not locked has view count <= the age of the question in days times 1.5 has 1 or 0 comments ... it will be automatically deleted.

Here are some comments on your suggestions and the topic in general: Professional mathematical interest in a question or an answer might well be a good necessary condition for MO but it will not make a good sufficient condition. If the unprofessional content can be cleaned away easily, the posts can and should be edited. If it cannot, then deletion is a ...

The related question on Meta.SE popped up today and I looked into this to see if I could figure it out. Looks like the misspelling of "Lipschitz" lead to a word that triggers single-flag deletion appearing in the comment, which was why the no longer needed flag immediately deleted this comment. For completeness, my answer on Meta.SE: In this case, the ...

There are a couple ways this is already done. When a question's score drops to -4 (or below) it is removed from the front page, and is therefore "hidden" from many/most viewers. In this case the question still exists undeleted, and will be shown if you view questions from another list (e.g., tag-specific lists, other search results, and even the "questions" ...

I think many wrong answers should be kept for the reason you stated. But this only applies to answers that have mistakes that are interesting or easy to do; it is only worthwhile to keep answers if people can learn from them. Comments and downvotes can indicate that the answer is not good, and ideally it should be also indicated in the body of the answer as ...

The title of the question mentions manual deletions, and Gil Kalai's answer voices his opposition to that. Let me answer quid's other concern: the system is currently automatically deleting some perfectly fine questions. I encourage 10k+ users to monitor the list of recently deleted questions, and vote to undelete reasonable questions that have slipped ...

I support not re-starting manual deletions. The situation today with automatic deletion and no manual deletion is better than it used to be in the manual deletions era and it is also better to avoid practicing manual deletion on top of the automatic one. (On pupular request: update) As quid explained: "What does not get auto-deleted are closed questions ...

I cannot speak for the people who voted to delete, but from my point of view, your answer had two problems. First, the English is written in a way that is quite difficult to parse. Phrases like "we can't do not choose $x$" do not occur naturally in the English-speaking part of the world. Second, it seems that the mathematical content in your answer (as ...

To the best of my knowledge, at the moment it is not possible to retract a delete vote: The feature request Ability to retract reopen/delete votes on Meta Stack Exchange is not marked status-completed. Other questions on Meta Stack Exchange about this problem seem to be often closed as duplicate of this post. Among the linked questions I can see this ...

Thank you for making your proposal. I see that you have put a lot of thought into it. My counter-proposal (that I haven't specifically run by the other moderators) is that content on MathOverflow be filtered the way it always has been. In detail: Content that is research-level mathematics will not be deleted. Content that is clearly not mathematics, or ...

To answer the comment question, "Why not just answer the question instead of discussing in comments?", my belief is that your question is both too general and too specific for meta. The specific question for meta was your question above, and (except for one snag), the specific meta question has served its purpose and could be deleted too. The general ...

I don't have a full understanding of the specific process which was at work here, but the action was performed by the Community User which runs automatically in the background. When it saw your flag that your respondent's comment was no longer needed, it did the work, I guess when it saw you deleted your own comment right before.

Possibly this is closer to a comment than to an answer - however, it would probably be too long for a comment. Re: I wonder, how that is possible because if I remember right, questions that have an answer can't be deleted. If a question has more than one answer or at least one answer has an upvote, it cannot be self-deleted. From the FAQ post How does ...

So, I have to ask you something. You say that we're "catering to professional appearance" and acting on "theoretical concerns about unprofessional-looking posts" without any "actual damage." I don't think that's true. I think that jokes like this are actually harmful. I admit that I don't have the best evidence for this, but I have evidence. I've read ...
