As a reviewer, if I see the authors lie in this way why should I trust anything else in the paper? The only ethical move is to reject immediately.
I acknowledge mistakes and so on are common but this is different league bad behaviour.
i clicked on 4 of those papers, and the pattern i saw was middle-eastern, indian, and chinese names
these are cultures where they think this kind of behavior is actually acceptable, they would assume it's the fault of the journal for accepting the paper. they don't see the loss of reputation to be a personal scar because they instead attribute blame to the game.
some people would say it's racist to understand this, but in my opinion when i was working with people from these cultures there was just no other way to learn to cooperate with them than to understand them, it's an incredibly confusing experience to be working with them until you understand the various differences between your own culture and theirs
AFAIK the submissions are still blinded and we don't know who the authors are. We will, surely, soon -- since ICLR maintains all submissions in public record for posterity, even if "withdrawn". They are unblinded after the review period finishes.
