That's basically correct, but see my reply to borovichok. I'm eventually going to have this run through all newly created topics and run the detection automatically (using an API to some websites or Selenium).
Sounds good to me.
Just suggested that in this case, the autotext be a little different, just saying it's suspicious content and not making a direct recommendation for it to be reported. That is, to be a more alert text for readers to be aware of, and not a condemnatory text.
Is it possible to configure your proposed JARPI to behave similarly to the auto ChatGT bots on Twitter? It triggers whenever someone tags it in a post and provides extremely good analyses. If I see a suspected AI post that I'm not sure about, I'll just @JARPI on the thread to determine if it's AI generated or not. I think it'd be better this way than you doing all of the work. Create JARPI and make it available to anyone who needs it.
