First of all, the question got closed only 7 hours after its posting: if this is because it was offtopic, that's fine; but calling an OP unresponsive after at most 7 hours from posting a question is extremely irrational. What if the OP went to sleep for the night? What if he was using a public-access computer in some library that he had to quit? What if he ...

The author of the question flagged and requested it be migrated to Computer Science. Although such questions are also on topic here, if the author requests migration, and the question is also on-topic on the requested target, I see no reason not to oblige.

My opinion is that we should be substantially more aggressive about closing questions than we currently are. In particular, I think we should be substantially more aggressive about lazy homework questions than we currently are. The community currently disagrees with me about this in aggregate, or at least as measured by the most vocal of people who have ...

This is a new feature, users with a gold badge in one of the original tags of the question can close as duplicate with a single vote. The rationale being that a user that answered that many questions in this tag is likely to know very well all the possible duplicate targets. This also goes for reopening, so you are also able to reverse bad duplicate closures ...

It should be neither closed nor downvoted, if anything because both are quite contrary to the whole spirit of the mathematical endeavor!

To be honest, I think the MO people acted incorrectly in this situation. Seeing it was a cross-post of a question they did not want, they should have simply closed (and possibly deleted) it on their side, instead of giving us a second copy of the same question. As it was the same question being asked twice, flagging it for moderator attention would have ...

There are so many approaches and reasons to upvoting and downvoting here (=Math.SE, not Meta) that it is IMHO largely pointless to attempt to codify them. A discussion is, of course, ok, if for no other purpose than to vent one's frustration. To simplify matters somewhat let me attempt to break them into three categories. It would be a miracle, if even a ...

I am so frustrated with no effort, copy-paste homework questions that I would support a one-flag close/delete policy on them. In my opinion, these are not on topic for MSE, and if they are, they damn well shouldn't be. It's important to keep in mind how many of these questions we're getting. In the past month I've found myself posting fewer and fewer ...

I don't think it's reasonable to expect readers to sit on the shell of a question for 24 hours, waiting for the question to hatch. A question is not a baby or even a chick. It's natural for users who read a question to call it as they see it (e.g., unclear) right away. Software already provides a recourse for on-hold questions: once edited by OP, they ...

Consulting others for every decision we make would not scale, so if we are sufficiently sure of our judgement, we act without consultation. The level of certainty that is considered sufficient depends of course on the graveness of the action to be performed, a suspension for example is more likely to be discussed among the moderators than things like ...

It seems a reasonable (not overly broad) Question to me. I made an edit to improve it. In the original post the motivation is described, reading a claim about the "foundation" of probability theory. The actual book and author were given in the first Comment. A sympathetic reading of the Question is that the OP wonders why a $\sigma$-algebra is needed to ...

If a new answer does not add anything at all it might reasonably be considered as "not useful" (in the given context) and thus could be down-voted. Basically, I think this suffices to control such activity. Of course, if a question allows too many distinct answers it is "too broad" and could be closed as such. I think it is difficult to give a hard and ...

Not all users actually had the close privilege thus there were not five votes to close even though the review-ticket lists more than five reviews with that recommendation. Likely this distinction should be made more clear on the ticket (as it is done for "delete" vs "recommend delete").


22

I think the best thing to do would be to post a CW answer containing a quotebox with the MO solution while providing both a link to the MO thread and citing who gave the solution. Justification: This way, the question will remain on MSE marked as solved, dissuading future duplicates. It is better to quote the text while crediting the author than only ...

Complementing Alexander's answer, a close reason of "lack of research effort" is, in my opinion, intrinsically bad for multiple reasons: it is impossible to ascertain how much research effort there was, "effort" is not a cop out for a poor question, it often gets dragged down to debates about how often students have "no clue on where to start" etc. If ...

A couple of points to consider: It takes five votes to close any question. If everyone saves their votes for some greater need, nothing gets closed. Do your share and vote. It's a community effort, and you have done a helpful share by giving 20 votes in a day. Some closure decisions are trivial, some are hard. If you're in a hurry, help with the trivial ...

The question is not spam in the literal sense of the word. And since the system is automatically trained by spam flags, you shouldn't use spam flags. You should downvote and vote to close. And you should let nature take its own course. You can should flag for a moderator's attention, to bring the account into their attention and hope it will speed the ...

TL;DR. Stack Exchange does not have any functionality to "retire" on-topic questions. The "Historical significance" lock reason is for very specific use cases where the question itself is now off-topic, and intrinsically so. The use of this lock reason to simply "retire" a question would be, IMHO, abusing that functionality. As is generally the case, ...

"No context" does function as a bit of a catch-all, and certainly 90% of the time, it is applied to "do my homework!" PSQs. However, there are several reasons it is stated like it is. Its "forms of context" list suggests ways that a question can be improved. For a user acting in good faith who happens to have asked a bad question, "lack of research effort" (...

I've had calc students make the $e^{x^2}=e^{2x}$ mistake before, as non-associativity of exponentiation does not come up very often in lower level coursework. Beings that $\int e^{x^2}$ is often brought up specifically as a first example of an integral with no closed form, I would expect many users who find this question through search to naturally follow ...

I usually stay away from meta matters, but this is an issue I feel strongly enough about to want to contribute something to the discussion on. To make this actually an answer to the original question, you should see it as an attempt to explain why, if it were solely up to me, I would have a policy requiring that users posting "homework" questions (broadly ...

You should just delete it. There is no reason to clog up the site with questions that don't need to be answered. The localized nature of your mistake also makes it unlikely that the question will be useful for future users. It is nice that you are concerned with the efforts of those helping you, but no answer was posted, and comments are intended to be ...

Here is some important context. There is, apparently, a massive campaign orchestrated by one user to delete all questions (and their answers!) if the question does not meet his standards of quality. This campaign appears to target not only recent questions, but every question, including questions many years old. As best as I can infer, this campaign has been ...

The absence of a set policy regarding open questions seems reasonable, since questions about them (including naive attempts to prove) may entail nothing more than high school algebra or a simple misunderstanding of some aspect of the problem. If a student accepts corrections, accepts that an idea is probably flawed, little is lost by helping. Sometimes it'...
