I have a large open source project and noticed the number of LLM generate PR is making it unmanageable. Every two weeks, I go in, kill all of them and when someone complains or asks why, I realize it was a real person and then I merge it.

is anyone else seeing this / fixed this problem ?

Yes, I "fixed" it by disabling pull requests on the repository. I'm still happy to pull from other people's branches (and do say so in CONTRIBUTING.md)

I mean an AI skill is perfectly capable of doing this exact same thing.
