@Xander has since correctly edited the question, so I removed my comment. His comment there is excellent, @Semiclassical.

I strongly suspect that it is a contest problem.

@XanderHenderson Excellent find!!

I am pretty sure that all three versions were posted by the same person, and that they are frustrated at being told that they have to ask a good question.

"Why are you on stack exchange? Here is my guess. Either for fun or to be kind and help people. "

hmmmmmmmmmm

@Semiclassical Are you sure you don't mean "stock exchange"?

lol

(for context, the above is from the comments of the OP in the above question)

Mostly that line caught my eye because it reminds me of why I don't really like the concept of "you should love the work you do"

because that's easily twisted to "if you truly loved X, you'd be willing to sacrifice anything in order to pursue it"

which is a tidy little pretext for abuse

@Semiclassical I mean, you should love what you do. But loving what you do should not imply that you love doing it for someone else.

As you say, it is a tidy pretext for abuse.

@XanderHenderson You should find the work satisfying, I'll agree with that

actually, I think I'll agree with the full statement as long as "doing it for someone else" includes satisfying the opinions of others

You're doing it because -you- love it, not to conform to the standards of someone else

@Semiclassical Precisely.

I have tried to engage with asker via comments, but so far no feedback from them.

One delete vote could be be used here: math.stackexchange.com/q/4057608/42969. No context, no improvement after 20 hours.

@Mathphile Hi, I have not met you here for a long time.

I suggest to delete this very vague answer: math.stackexchange.com/a/642303/42969. It is unclear how that "hint" leads to a solution.

Totally bogus 'answer' because the stated limit is simply zero...

@user21820: downvoted it. But it will take a while before it is up for deletion.

@ParamanandSingh Thanks. I have no idea why nobody before me had any issue with it even though it is obviously false. Anyway, I also don't know why the accepted answer makes things so ridiculously complicated, and only celtschk pointed that out (besides my answer).

@user21820: thanks to @Peter a lot of bad answers are being deleted nowadays from this room. There is so much content on mathse that one can always miss such bad answers.

@user21820: on the other hand not every case of bad answer is easy to handle from this room. Even i am waiting for conclusion on "divide 100% by 3" which you raised in mods office.

@user21820 In fact a nonsensical answer (at least as it is written down). Who knows why it received 4 upvotes.

@ParamanandSingh The main problem are the heavily upvoted bad posts , but in this case we can do nothing, I guess. So we have to concentrate on the massive downvoted posts no matter how old they are. The automatic deletion takes too long and is too unreliable.

@Peter While I'm happy to see those massively downvoted posts go, I personally don't know how much effort is worth to be spent on them, because people do already ignore anything with score ≤−3 (since SE fades them). However, in case you aren't aware, answers are never auto-deleted, so yea if you want them gone posting them here is probably the best way.

@Peter Inexplicable upvote:downvote ratio often shows up on HNQs haha..

@user21820 I heard something else (if I remember right "roomba"), but whatever it is, it apparently does not do its job.

@Peter That only runs on questions with low score.

@JoséCarlosSantos Thanks! It's gone now. =)

Please look at these two questions: math.stackexchange.com/questions/4056593/… and math.stackexchange.com/questions/4059104/… They are not identical but they are asked by two different users about a very similar topic and use the same distinctive notation for the covariance and variance, around the same time. This seems very suspicious to me. Any thoughts?

Twice upvoted PSQ.

I always feel torn on questions like this: math.stackexchange.com/questions/4059509/…

on the one hand, it'd be fine to close this as duplicate of math.stackexchange.com/questions/75130/…

but that feels like i'm doing the mere work of "searching the archive" for them
