I've observed this phenomenon for a while. The people deleting these pretty much do nothing else. They are some how considered valuable contributors. Something I've mocked loudly. The effect is that some topics/categories have wild outgrowth of articles even the best of us would doubt necessary but certainly wouldn't care enough to attempt to delete it. Every popstar, every album, every song on the album, covers of it, each their own article. It would be wild if STEM editors got the memo.
Who the hell would not want an article about a tractor company? Tractor are more important than discography. It gets even more stupid if we assume your articles really needed work. Who is to do the work if it is not allowed?
They should just ban the deletionists starting with the ones who didn't contribute a single sentence for years. Filling talk pages with nothing that creates articles.
The worse case I've seen was a guy creating articles about (mostly old) books for many years followed by this giant caravan of deletionists who sometimes deleted the article immediately, sometimes after a week, sometimes a month, sometimes they exchanged troll messages among their own for a whole year. Eventually they deleted the articles faster than he created them with ever cheaper excuses until eventually the person creating them was the excuse for deletion. Thousands of articles gone, all good articles. I know all of the guidelines, I know when it should be good enough.
