There is a very useful website at https://beallslist.weebly.com/ that provides a great deal of information on predatory publishers. It provides links to DOAJ and JCR to check a journal's claim to be listed, a list of potentially predatory publishers and standalone journals, Bealle's original criteria for determining predation, and an updated journal evaluation tool.

Citing Shamseer, et al., BMC Medicine 15:28 (2017), it suggests these characteristics for predatory publishers:

Thanks for sharing the information.

Hi,

A predatory journal is one that makes false promises that do not conform with science standards such as a promise to circulate you paper among many journals. The science journals demand copyrights from an author, so this conduct is unacceptable. A predatory journal will hide the fact that it charges fees for publication, until you paper is accepted for publication and then you are surprised by a request for payment. A predatory journal will include well known persons in their editorial board without asking them if they are willing to be included in this board. And so on...

It is useful to identify the predatory publisher.

I try to put the name of the publishers who are probably predatory and publishes journal from India. Likely, If we get the name and their country of origin, it is easy to isolate them. Besides, time to time discussing about predators people would be more cautious. So many people in high position either knowingly or unknowingly support these predators and that creates the problem.
