Peer review was never supposed to check every single detail and every single citation. They are not proof readers. They are not even really supposed to agree or disagree with your results. They should check the soundness of a method, general structure of a paper, that sort of thing. They do catch some errors, but the expectation is not to do another independent study or something.

Passed peer review is the first basic bar that has to be cleared. It was never supposed to be all there is to the science.

It would be crazy to expect them to verify every author is correct on a citation and to cross verify everything. There’s tooling that could be built for that and kinda wild isn’t a thing that’s run on paper submission.
