It would help to know why a post was deleted, I believe in this case automatically by a MO monitoring robot. I am not judging the decision, but would like to know why, to avoid asking such questions in the future, that could also be deleted for unknown reasons.
The question I am referring to (not sure if anyone can still see it) is:
https://mathoverflow.net/questions/398151/some-stuff-related-to-the-twin-prime-conjecture
It's not the first time one of my questions is deleted, but have no idea what caused it, so I have no idea how to prevent it in the future.
This is not a criticism, I manage myself a community website and also delete posts without providing reasons (it usually falls in 4 categories: irrelevant, too basic, spam, or self-promotion / commercial post).
Any help is appreciated. As far as I know, I did not violate any MO rules, but I could be wrong.
Thank you for your help.
