Publication metrics. This has been a problem for at least the last few decades, especially when it comes to papers from some parts of the world. Before the current breed of low quality journals, we saw this happening with conferences that were often branded with professional societies like IEEE, but if you looked carefully it would be “IEEE Section of (random place in Asia)” and not a conference sanctioned by IEEE itself. Those used to be full of garbage plagiarized papers and junk. I think the idea is that nobody usually reads the papers when they make a decision based on publication metrics, so pumping a CV with garbage often goes unnoticed. It’s not a wise practice: in many places getting caught doing this would be a career ender.
