I'd not heard of Fengkai Group before I saw their LinkedIn advert. They're offering paid positions to be a guest editor for special issues in SCI- and Ei Compendex-indexed journals (the latter is Elsevier's engineering index). That's weird, I thought.
Csaba Szabo has heard of them: he commented on his guest post on Leonid Schneider's blog about uncovering paper mill activity, at https://forbetterscience.com/2025/05/19/a-sting-inside-a-papermill/#comment-762891, to note the worrying approach Fengkai made to him in May.
Christopher Tang got in similar email in June: https://www.linkedin.com/pulse/lets-stand-up-against-unethical-research-behavior-christopher-tang-eur3c
More than 20 of my LinkedIn connections follow Fengkai Group and several are connected to the LinkedIn account that posted the advert.
We all need to be careful not to legitimise questionable organisations by associating with them.
