One of the reasons for closing a question is as follows:
unclear what you're asking
Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question.
I get that there are a lot of unclear questions, and that we need to let the askers of such questions know that they need to majorly rephrase and fix up their question so that we can answer it. But what's the point in closing such questions?
Say the person does fix up their question and make it understandable, now we just have to go through all the shenanigans of opening it back up again so someone can answer it. And even if they don't end up fixing up their question, all closing it does is make it unanswerable, so even if somebody manages to decode it and thinks they can answer it they can't!
So, why do we close questions as unclear? What harm does an unclear question left open do us?
