"[3] Chinese researchers have been identified as particularly prevalent customers of paper mill services.
In early 2022, Times Higher Education and the Science Magazine News department covered a report exposing a Russian paper mill company International Publisher Ltd.[4][8] The report identified hundreds of published academic papers where positions for authorship had been sold through a Russian website allowing researchers to pay for academic prestige without requiring legitimate research contributions.
[7] Beyond collusion between editors and International Publisher Ltd., many legitimate research papers also sold authorship unknown to the journal editors, and were ultimately accepted in journals published by Elsevier, Oxford University Press, Springer Nature, Taylor & Francis, Wolters Kluwer, and Wiley-Blackwell.
The problematic papers were linked to Hindawi, an Egyptian publisher of about 250 scientific journals that Wiley acquired in 2021.
The article also warned that artificial intelligence was going to make fraud more difficult to detect.
