It is well known in my field that a particular good journal has an editor-in-chief that frequently asks authors to cite a particular (largely unrelated) paper whenever he has the chance.
Looking at google scholars citations of this particular paper, you can notice that it has a large amount of citations from this particular journal. Reading the papers you can almost see the struggle of the authors trying to cite an unrelated paper.
This has been going on for years.
What can I do to try to stop this? I frequently avoid submitting to this journal due to this issue.
