If you can at least attest who is responsible, other tests for AI-generation might be applied, with reputation following from that.
Sadly, that's bullshit most of us didn't ask for, and it's turning up all over the place, e.g., among book and short-story publishers, journalism, academic publishing, as well as blogs and social media.
Attesting who is responsible is more of that "bullshit most of us didn't ask for". I'm not interested in identifying myself so some cretin can know whether I am, or am not, an AI... particularly when the vast majority of posters on any platform act like NPCs anyway.
