For what it's worth, I just tried out Pangram to hopefully get some insight about why it concluded my text was AI generated. But no, it doesn't give any reason.

Note : the message I have received privately from Catherine doesn't answer any of my questions.

Thank you Fran. Can confirm taking legal action is very unpleasant.

I don't know either and flagged it to the mods immediately. The only AI use I know of was a general sweep for language mistakes (English isn't my mother tongue). Some corrections were made by my lawyer. All in all, minor edits, that's it.

I'm in Lisbon until Feb 11...in the morning unfortunately. I'm happy to hang out until then 😌
