In the past, mostly these computer-generated things were accepted in computer science and engineering journals in China, and every scientist has received spam soliciting contributions to these more or less fake journals and conferences. I get several emails a day, literally. So the fact that those “journals” published goblygook is not exactly news. The fact that a journal published by Springer and IEEE got taken in is a little bit more surprising. In the molecular biology journals where I submit, the peer review process entails pretty careful scrutiny. As for the idea that fraud in science is generally increasing, there is not hard evidence for this one way or the other.
