This medium article might be a good start, also check references to actual research at the bottom.

Thanks. i did a bit of research this morning. i read a couple of articles:

From this one: https://writehuman.ai/blog/how-accurate-are-ai-detectors#!

Imagine the University of Kansas researchers created a tool that can spot AI-generated content in research papers with an amazing 99% accuracy.

In contrast, OpenAI's Classifier achieves only a 26% success rate and mislabels a human written work as AI-generated content 9% of the time. Another tool, AI Writing Check, predicts its accuracy to fall between 80% and 90%.

So it depends which tool is used, in part anyway.

This one https://www.makeuseof.com/accurate-ai-text-detectors/ has GPTzero (which i just happened to use) at the top of the list.

But still, in the case in question,
a/ from looking at past actions and attitude (from the aforementioned reply by hivewatcher),
b/ from my initial sense of something not being right possibly confirmed by GPT zero with 98% possibility on 1 post & 85% on the other, and
c/ from diggndeepers failure to appeal in HW discord either this time (or presumably last time or in discord (i'm in the room & posted a message) and his actions toward me, i'm inclined not spend take more time on it unless i hear from him.

i've spent several hours over the last weeks monitoring HW discord appeals channel (& other channels) & looking at the posts in question. Having approached it from a neutral stance (even though i'd built up a negative perspective over the years due to all the complaints about HW i've seen), my view now tends toward HW doing not a bad job (recently since i've been looking anyway) and getting lots of abuse from what appears to be clear cases of chain abuse.

incidentally, i removed my downvote from the post last night. Don't know why, but i did.
