I think the comment you linked doesn't sound like AI at all, though. I do empathize with people worried about getting falsely accused of using AI in their writing, either hypothetically or in your case in actuality, but at the same time I kinda just think that's a skill issue on the part of the accusers.

This is very much a general "English reading skills" kind of test. A lot of people don't speak English as a first language, in which case I think it's entirely forgiveable. It's hard being attuned to things like writing style in a foreign language (I know from experience!). It's a pretty high level language skill, all things considered. And even among those who do speak English as a first language, there are many in this industry who don't have strong reading skills.

I do believe that personally my hit rate for calling out AI content is likely very high. Like many of us I've had the misfortune of reading more LLM output than is probably healthy for my brain.

One quick point:

>Those sentence constructions that are "tells" were also learned from good writers though.

I don't agree at all, I think the LLM style of writing is cribbed from like, LinkedIn and marketing slop. It's definitely not good writing.
