Third option is correct. I ran OP's text through many AI detectors and all of them gave AI-generated indicators, so I fired up JARPI to send the warning.
So basically you browse the forum normally, and when you think an OP was made by AI, you submit the topic for JARPI analysis.
Then it will analyze and if it concludes that the text was generated by AI, it will post the ad. This is it?
Thus, you stop worrying about analyzing these cases in detail, and you can continue to browse the forum normally looking for other cases. Seems to be an interesting tool, to free your time from those boring analyses.
Honestly, I find this option much more useful and interesting than answering repetitive topics.
