On December 12, 2019, a new article was published on Nature with a definition of "predatory publishers" followed by an interesting comment.

The already known Ten myths around scholarly publishing greatly reduces the issue of predatory publishers; one should always take a look at Retraction Watch, which daily monitors the number of retractions of articles published in high-impact journals. Indeed, the practice of falsifying or creating ad hoc data seems widespread. In this regard, this article demonstrates a direct correlation between the journal's Impact Factor and the number of retractions, with the paradox that the "best" journals seem to publish the "worst" science.
