What can I do as a reviewer when I find a manuscript which I have recommended revisions has been published without any changes? I seriously doubt the peer review process in the journal.
Dear Rejeesh C R, this is indeed rather strange and worrisome. I have a certain feeling that this could be a hint that the journal is a predatory / fake journal if they just ignore your review. You should check at BEALL'S LIST OF POTENTIAL PREDATORY JOURNALS AND PUBLISHERS (https://beallslist.net) if this is the case.
