I think this user is already temp banned. If reports for these posts are all marked as "Good" I will update the OP with the new criteria.
My reports on JayTrain's posts are all good. But it is an obvious case. I guess it's about that moderators should see that it is a violation, and if there will be a less obvious case they can probably be not content with just numbers from detectors.
The case mentioned by lovesmayfamilis would be harder. It looks like his posts were written with the use of AI, but it was rewritten a bit to pass the AI detection.
