Does anybody know? Some weeks ago I saw something like a hashtag or website (I don't remember). It was a movement for doing peer reviews only if the publication is open access.

Something like "No OA, no peer review"...
Anybody knows of this?

The closest I can find is this old discussion on a Times Higher Education article (the original article is paywalled, but you can read it via 12ft.io):
