Now it is very complicated to get at least three scientists who want to review papers for free. I think it is because almost all journals charge to publish, and they are very expensive, so we would not like to give our work for free, but there is also a great number of new journals that need to get reviewers for free at the beginning. It is a terrible situation that only benefits the great editorial boards. And, in the middle, some predators appear and try to defraud as much as possible of the money. I give you the question, sincerely: "Would you review some papers for free, for a new and small scientific journal?"
