>>4551>like that dumb -- thing they do that nobody else on earth ever does.I resent that. I regularly used em-dashes in longer posts until the whole world suddenly latched onto that as an AI bogeymarker. Same goes for semicolons, enumeration in threes, etc. Most grammar and punctuation that lay people call AI-like is just what used to be taught as good style in writing classes.
In my experience, the biggest giveaways are bland vocabulary, needless verbosity, and whatever you call that essay-like structure of "Introduce what you're about to say, then say it, then summarize what you said". That last one goes double when it's used in an informal context or as a reply to a much shorter post.
(Ironically, AI will probably flag this post as AI because I overcooked it.)
