10 questions in one PSQ... mind = blown

One close vote missing on this PSQ – I wonder if the “post and answer and immediately self-delete it” method should be seen positively (the answer is only undeleted after the question author shows some attempt) or as a FGITW way of reserving the first position in the answer list :)

D1, D2, D3.

D4, D5, D6.

D7, D8, D9.

D10, D11, D12.

Nonsense as Noah pointed out. @JoséCarlosSantos @XanderHenderson

C1, C2, C3.

C4, C5, C6.

C7, C8, CH dispoof obsession.

@MartinR Flag such questions for moderator attention. It's a negative behaviour.

@MartinR That lousy PSQ which two PSQ-lovers have upvoted is also up for deletion now.

@XanderHenderson This too is up for deletion.

@MartinR To put the behaviour in the best possible light: if the question is improved and the answer is a useful answer, then I see nothing wrong with writing an answer and then deleting it until the asker improves things. Answers are put in random order (with an accepted answer put on top), so posting first is not as relevant as it might be in other fora.

That being said, I, personally, don't like this behaviour, and appreciate flags.

@XanderHenderson Besides what you said, I suppose you already know that users who do this kind of thing are not likely to abide by the closure all the time, and may undelete even if the question is not reopened. Ultimately the point is that they are circumventing the closure.

@user21820 If a user were to undelete an answer after the question is closed, that would certainly appear to be a circumvention of the closure. Such behaviour is certainly in contravention to standards and norms on the site. Please flag it if you see it.

@XanderHenderson But that's precisely the problem. This kind of behaviour cannot be easily found, because we can't sit around watching closed questions.

So far, I think I saw it once or twice (posted, deleted, undeleted after a while) some time back. I suppose an SEDE query might help here, since undeleted answers do show up in SEDE. But I don't know how to use SEDE.

@user21820 I know. There is not a good way to track it. But if you see it, please say something. :\

@XanderHenderson Yup. I definitely would if I see it again.

@user21820 The lousy PSQ has been deleted.

@JoséCarlosSantos Thanks for your excellent vote!

=P

@XanderHenderson: Often he doesn't even bother to delete an answer to a PSQ. In this case, a double-PSQ.

@user21820 Ugh... and that is certainly a duplicate many, many times over.

Oh, look! It is a duplicate! And I answered it. :\

@XanderHenderson Lol! I see someone didn't like your answer. I suppose I also prefer Sri-Amirthan Theivendran's answer haha..

@user21820 Yeah, that answer was a random downvote which just showed up one day. I suspect that it is one of the petty downvotes that I get from time to time. :)

@XanderHenderson Thanks for your feedback!

@ArcticChar D9 can now be deleted.

This user is definitely trying to get answers to their homework with no effort. Note the exact same wording in these questions: math.stackexchange.com/questions/3842512/…, math.stackexchange.com/questions/3842565/…
