Motivation: Our university has asked us to provide contacts for possible referees for our university for the QS ranking; apparently this "find your own reviewers" system has a 40% weight in that ranking. I find the whole system flawed and open to gaming, and I am considering participating in some sort of boycott.
It is a widespread opinion that academic rankings are harmful, so I was wondering if there is any ongoing boycott that I could participate to.
For instance, mathematicians have boycotted Elsevier in the past, refusing to publish, review, and/or take editorial roles in journals from that publisher. If there is an organized movement like that for refusing to take part in academic rankings, I would be interested in a pointer.
