It would be helpful if there was a way to show the reasoning behind deleted submissions. Like a quick note on [dead] pages that explains why it was killed, just like you did here. That way, people won't keep resubmitting the same story over and over, which makes it easier on everyone.
"if there was a way to show the reasoning behind deleted submissions"
I don't know why they don't do this but I can see why they might not do this.
By stating a reason you then invite questions around the decision and waste time in addressing those questions. By not stating a reason many decisions like this will simply go unquestioned in a "nothing to see here move along" kind of way.
