Disclaimer: Don't flag broad, as it's all very interconnected and can be answered well in one post. One shouldn't repeat the whole story again and again. Also, I had exams so had avoided discussions back then but kept checking the site.
was a question on 13th Sept with missing code formatting and to guide OP in case they post it somewhere, I edited it and added script as that is what we have for such questions. Then I left a comment suggesting SO, searching for related questions and reading help center, and asked the python version. This comment was deleted.
I'd love if someone could post the original comment as I forgot what it was.
Two answers were given, one claiming version problem, one about an alternative approach. I downvoted both.
To avoid serial/ revenge voting accusations:
For nohillside's answer, it wasn't really a great answer, I am pretty sure some way or the other, people could get a file name with a custom prompt and suggesting newer version for it didn't seem appropriate to me.
For jmh's answer, I am discussing it in the comments, if the answer or the original question doesn't get deleted. I tried OP's code on python3 and it worked, their code worked too. There's no way to tell if it fixes what the problem in their setup is. Also, it should be code format, not quote, generally.
Then the post was flagged by Mark (and maybe by some other <3k rep user) and nohillside put it on hold 2 days ago, after deleting their own answer. (oh! that explains a recent +1).
My queries are:
Did I go wrong by adding the script tag?
Why was the comment deleted which IIRC didn't contain any objectionable content? It was better to have it since it was accusing the post of being off-topic which might get seen by some other moderator if it is a borderline case. It could have been edited too by the mod.
Why did nohillside as a mod answer a potentially off-topic question?
Didn't my comment matter while Mark's close vote did, for the same goal?
