A (very small) silver lining of writing a metareview with dozens of spammed LLM rebuttals is that occasionally the authors' unproofed generated response gives the game away by saying something like "Your criticism is spot on—it points to a serious oversight that requires a major revision."

Good thing we don’t have a long history of people incorrectly projecting human traits on computers and overestimating what they’re really doing.
In computer science, the ELIZA effect is a tendency to project human traits—such as experience, semantic comprehension or empathy—onto rudimentary computer programs. ELIZA was a symbolic AI chatbot developed in 1966 by Joseph Weizenbaum that imitated a psychotherapist. Many early users were supposedly convinced of ELIZA's intelligence and understanding, despite its basic text-processing approach and the explanations of its limitations.
