Do closed questions ever get deleted and, if so, is reputation recalculated (subtracted) for that question and all its answers?
What happens here in meta, given that feature request "questions" are closed when they are completed?
Why would you delete a question? Isn’t closing it enough?
Some questions are of such poor quality that they cannot be salvaged. They’re literally nonsense. Not every byte of data that is created in the world is infinite and sacred.
Some questions are so incredibly off topic that they add no value to a programming community.
The mental cost of processing these closed questions is not zero, particularly for users who are actively engaged and scanning questions to find things they can help answer.
If users see a lot of closed questions, they’ll note that we don’t enforce the guidelines, so why should they? Without any final resolution, asking questions that get closed becomes something we are implicitly encouraging — a broken windows problem. If this goes on for long enough, we’re no longer a community of programmers who ask and answer programming questions, we’re a community of random people discussing.. whatever. That’s toxic.
If enough of these closed questions are allowed to hang around, they become clutter that reduces the overall signal to noise ratio — which further reduces confidence in the system.
Moderators (Edit: more specifically, users over 10k reputation) can vote to delete a closed question after 48 hours and it takes 3 of our votes to delete it.
After that it can be voted to reopen (Edit Olafur says that it is NOT reopened, just undeleted still in closed status) past the delete status using the same mechanism.
As far as I know, rep is NOT recalced, which can make it a little confusing since you will have rep awarded or lost at some point but no longer be able to see how.
Edited to add: Additionally, Moderators, in the ♦ sense, can delete any question, at any time
Do closed questions ever get deleted?
Yes. Questions are only deleted if they are very low quality, spam, illegal, very localized or doesn't add value to the community. A moderator can delete it right away, high rep users can vote to delete it.
is reputation recalculated (removed) for that question and all its answers?
Yes. Not right away, but when there is a rep recalc this is fixed for each user.
What happens here in meta that questions (features requests) are closed when they are completed?
They are not closed, they are tagged as status-completed. If there are answers you can accept the one who best describes the feature that was added and how it works, or something like that.
I believe by default they are not deleted, but a moderator can delete them. I think this is helpful, especially in the case of dups because there are many ways to ask the same question, so it provides more "pointers" to the question. Additionally, I believe deleted questions do eventually result in recalculated rep.
