I had a deeply maddening experience at one job where somebody was reviewing a Typescript PR of mine. In their first copy-pasted review there was a suggestion that I do something slightly differently; it wasn't something I had a strong opinion on and they were more familiar with the codebase, so I made the suggested change to just keep the peace and get the change out.

In their followup review, again copy-pasted, it made a new recommendation - which was the way I had done it originally. Absolutely no human conviction behind the review, just copy-paste ping-pong feedback.

The way I got around it was by implementing my original change again, and writing a stronger defense of it, with lots of references, and calling out as many downsides to their initial recommendation as possible, in an attempt to prompt-inject and overwhelm whatever model they were feeding my work into, and it worked. It gave me a very grim view of the near future.
