There’s actually nothing different in the detection for bans vs tagging-encouraged. It’s all the same signs and patterns as outlined in Soren’s document, The difference is in how much it permeates the entire story, almost like every paragraph shows signs of it. If there’s hesitation, I have access to high quality paid detectors that are much more reliable than the free crap (still never perfect), and these stories ping consistently in the 90%-100% likely AI ranges in 2+ detectors. They’re rarely needed. But basically, all the patterns highlighted by Soren, but on steroids.
Also, these texts show clear signs of not having a human touch at all guiding the writing.
