Nonsense, it's easy: you just need a social process like Linux has. Patches are ignored unless you've proven yourself to somebody. Start by participating in technical discussions on IRC or the smaller mailing lists; do that for a while before you submit patches. For smaller projects: "if I don't know you, I don't merge you".

Linux's LLM policy allows AI-generated code because the project was never vulnerable to this DoS attack in the first place. They kept the social defense they've had for decades.

The killzone here is Github culture, where people decided it was normal to accept code from anonymous randoms with anime avatars. They're doomed.
