Has there ever been a strike of peer reviewers? I know peer reviewing is done freely and voluntarily, at least I think for the most part, so I am not sure strike is the best way of calling it, but it gives the idea. With all the recent discussion about open access and overworked researchers that relate to the publishing cycle, I was wondering if there has been any protest, or strike, or talks for a strike by peer reviewers.
Researchers have refused to review for Elsevier, as part of the Cost of Knowledge boycott, which 


Objects to exorbitantly high prices; and 
Objects to measures that restrict free information.


The initial success of the boycott was summarised in 2014 by Sir Timothy Gowers (Fields Medal recipient):


  A little over two years ago, the Cost of Knowledge boycott of Elsevier
  journals began. Initially, it seemed to be highly successful, with the
  number of signatories rapidly reaching 10,000 and including some very
  high-profile researchers, and Elsevier making a number of concessions,
  such as dropping support for the Research Works Act and making papers
  over four years old from several mathematics journals freely available
  online. It has also contributed to an increased awareness of the
  issues related to high journal prices and the locking up of articles
  behind paywalls.
