This question shows that there are at least three websites that attempt to track predatory journals. I recommend checking all three for the name of your candidate journal.
Here is a site with lists of predatory publishers and journals, which seems still to be updated: https://beallslist.net/ It was mentioned in a new discussion on this topic: https://www.researchgate.net/post/What_is_the_accuracy_level_of_Bealls_efforts_https_beallslistnet_in_tracking_predatory_journals_across_the_world
The following discussion may be of interest to those who are interested in avoiding predatory publishing themselves and in warning their colleagues and students: https://www.researchgate.net/post/Predatory_Publishing_How_to_solve_the_problem
There is not a clear characteristic of predatory journals and it is very difficult to try to give a precise definition, because these journals try to fill all criteria of "normal" journals, at least at first sight.
However, it seems to me that their common point is the following:
A predatory journal is a journal which has only one option to publish: "The paid open access option".
Unfortunately, there are a few serious journals which enter in this definition. In order to be fair with these journals, a "white list" must be carefully extablished whith highly competent and honnest people.
However, things are not so simple. some great publishers use also "paid open access" option because they integrated several "external" (not really managed by them) journals in their websites.
Indeed, people ask themselves “is this (particular) journal or publisher predatory” and want to end up with a yes or no. As you indicated yourself this is (sometimes) quite difficult. There might be some miscommunication, but I honestly do not see how your “compact definition” will help.
First, there are more and more journals dedicated to open access and a growing number of publishers are full open access publishers (PloS, Frontiers, Hindawi, MDPI, Bentham Open) or have a portfolio of journals exclusively open access (like the Springer Nature series BioMed Central (BMC) journals). They work according to the "The paid open access option" in other words they charge APC’s and have nothing to do with predatory publishing. Your ‘definition’ sounds to me too much like ‘open access equals predatory’ see also this excellent paper on this ‘sentiment’:

Second, how does one determine that “a journal that has only one goal: to make a lot of money as fast as possible cannot claim to contribute to the development of scientific research.”? Sure, there are obvious cases like the notorious OMICS publisher, or this example discussed here on RG:
I have tried to define the predatory journal according to my personal belief. When I say "try", it means I'm not claiming to have the truth. You have every right to challenge and reject my definition.
However, when we talk about something it is because we are able to define the thing we are talking about, otherwise we don't know what we are talking about. If you have a definition of "predatory science journal", I'm ready to analyze your definition. If you don't have one, then the same word can mean different things to different people. There is likely to be a lot of misunderstanding.
Instead of a definition, we also can give a list of predatory journals. But here, it is worse, because on the one hand, we do not know on what basis the list is made and on the other hand the one who makes it, gives himself the quality of a superior person in competence and honesty, who moreover sets himself up as a judge.
Hi. It is also suggested to check the details in the particular Journal website, H index, impact factor to understand whether they are predatory or good journal. Thanks
