There is nothing to comment on the Wittau paper except that AI & paper mills are the second largest thread to science already.
Honesty of publications is fundamental in science. Unfortunately, science has an increasing fake paper problem with multiple cases having surfaced in recent years, even in renowned journals. …
We investigated 2056 withdrawn or rejected submissions to Naunyn–Schmiedeberg’s Archives of Pharmacology (NSAP), 952 of which were subsequently published in other journals. In six cases, the stated authors of the final publications differed by more than two thirds from those named in the submission to NSAP. In four cases, they differed completely. Our results reveal that paper mills take advantage of the fact that journals are unaware of submissions to other journals.
