Suppose your worthless article didn't accept in other journals, Is it ethical to pay money for publishing that in a Open Access journal that MONEY is the more important condition they have for publishing?
If there is no innovation in your paper and some journals have not accepted it, you should try to work hard and reinforce the scientific base of paper. Then you can resubmit it on those journals. But after several rejection from valid journals, if a specific journal's editor told you give some amount of money to accept and publish of your paper, it is logical to doubt about the validation of that journal. As all of us know, there are some fake and hijacked journals which are in BLACKLIST. you can follow the bottom link to know more about them:
Most OA journals (reputable ones) will run your paper through peer review process to judge if it is ''worthless'' or not! if you believe your article will make a contribution to the scientific community, submit it. The money you pay after acceptance isn't a price for their ''favor'', you pay for owning the copyrights and making your article free for all.

It is not unethical. If your article is really worthless then nobody would care if you published it or not. And even if you get an accidental citation, it wouldn't make a difference. But if you believe your article is worthless, then you shouldn't try to publish it in the frist place.
On the other hand, just because your article wasn't accepted in a number of journals, doesn't necessarily mean it's worthless. The same paper might be rejected if the author is unknown to the editor but can very well be accepted if the author is well known (believe me, i know of such cases). Of course, there might be other reasons behind that - an experienced author knows how to present the same infromation better so that the editor and the reviewers like it (like add many references (citations) authored by them).
I believe that the researcher who does this has a problem either in his place of work or is scientifically weak and therefore there are many fake and hijacked journals that live on such researchers .
Not publishing can be just as unethical (selective reporting is a big issue in many fields). It depends on how you define 'worthless'. Is the design or methodology worthless, or are your results not significant? Paying to publish an article just for the purpose of publishing it is a wrong reason to begin with. However, the way the publishing process works in many journals can sometimes still be considered as unethical as well. Fortunately, a lot is already been done to make publishing more transparant and honest; for example see DOI: 10.1126/science.aab2374 or DOI: 10.1038/s41562-016-0021
Is this an author problem or journal problem? Is it ethical to have journal that publish worthless papers for money? Open access in general doesn’t mean worthless journal, many high ranked journals are open access. I believe any scientific research could be published in a suitable journal and its value is something subjective but can be measured later by the citations
The only reason I can think of for anyone to do such a thing is to have numbers. I don’t know, however, what advantage high numbers, but no quality can give, I don’t know. It is certainly not ethical.
