Since quite some time, the amount of new incoming higher level questions is decaying and the number of very basic ones is increasing, but the current inflood of bad homeworks (the good ones I appreciate and upvote) and very basic questions of non physicists and people who have almost no physics knowledge of their own, is unprecedented I think.
Here are some examples of what I mean:
Ok, parts of them get closed or migrated, if they are just posted on the wrong site here etc ...
But the really worrying thing is that a not negligible part of these homework and very low level questions get (even highly) upvoted and answered by very basic answers which are upvoted too by the present population of Physics SE, and sometimes even flags saying that these questions should not be here for the one or the other reason, get declined!
The About of Physics SE still says
*Physics is a question and answer site for active researchers, academics and students of physics and astronomy.
So my main question is:
What can be done to counteract the overtaking of Physics SE by homework, very basic, and laypeople questions to make it a better and more attractive place for active researchers, academics, and students of the site topic again?
I know that similar questions have been asked over and over again here on Physics meta. But obviously the issue has never been seriously addressed which is, as I guess, among the possible reason for the current flood of really low level stuff.
People who ask these low level questions seem to be less knowledgeable on physics or maths than the visitors of Prof Strassler's site the purpose of which is explicitly to explain (particle) physics to laypeople. And the atmosphere of the site starts to be "Quora-like", as (almost only) short, basic, equation free, and in popular language formulated posts get high upvotes, activity, and attendance whereas slightly higher level, more sophisticated, advanced topic, and in particular technical posts almost tumbleweed meaning they get low views, low votes, no answers, etc ... these days.
A bad side effect of the current state is that if this keeps going, the site will be governed by people who like and prefer this increasing basic Q&A, because it is them who are gaining the most rep so it will be them who have the power to closevote and access to other moderation privileges, even if they have no (deep enough) physics knowledge of their own to decide what is a good legitimate physics question and what not for example, what the (intended to be community of physicists and students) needs, etc. whereas the initially targeted by the site audience and its needs gets pushed back.
So, if the targeted audience should still be the one described in the About, something has to be done.
