The style in which that post by Ophelia_SK is written seems exactly like chatGPT. I can’t quite put my finger on what exactly makes me feel so strongly, but it’s something to do with how sentences and paragraphs are constructed. They always have the same cadence with the commas and how thoughts are laid out. It’s got that generically positive tone as well.
Kinda cool though, I feel like I’m becoming able to spot these. It’s like being able to spot a photoshop by the pixels. I’ve seen quite a few shops in my time.
