I had a weird experience with what I assume were AI-generated or assisted PRs to my analytics tool. At first one PR appeared, with a strange name that looked like some kind of hash, with a timestamp and the name of the AI tool. It was a bit dirty, so I commented that changes need to be made. Not sure whether the followed PRs were the response to my comments, but anyway, I got 5 more PRs that were doubling each other for the most part. Also, they were inconsistent in terms of intentions. All of them contained an important fix, but also all of them contained a lot of noisy changes that were different each time. The PR's author didn't communicate back. They were just generating these PRs. I blocked the author's account and created a PR with the fix myself, mentioning that account. No matter the whole weird experience, they helped me with the fix.

This also reminded me about my experience with reviewing AI-generated PRs with changes in hundreds of files. It couldn't iterate as well, force-pushing new code every time I was leaving comments.
