Foreword: There's a particular question that motivated this question, but please advise whether I ought to cite it. I haven't yet, because I don't want to target specific individuals. In my case, my question cited 3 reputable sources, but was professed to lack sufficient research, and closed. Then it was reopened even though I didn't add any more resources (but I edit the OP slightly).
Actual question (TL;DR): Suppose all 5 closers chose a close reason that masquerades as, in order to distract from, their real reasons (eg personal bias).
Once this happens for many questions, not only the poster, but other users, must expend needless time to petition on Meta, and to reopen the questions.
So what can be done about such closures and closers?
