More AI-like writing styles??

is it just me or some of the fanfics im reading seems like it was written by AI? The writing style in uncanny. and no I don't mean fanfics that have complex language, I love those! it's like these fanfics genuinely just seems like Ai wrote it or re-wrote it. I don't know if some of these authors are asking AI to rewrite their stories of theyre giving ai prompts, or if they just have AI-Like writing style. As someone who got addicted to using ai in the past(dont worry, I do not use AI now and do NOT condone using AI ever) istg the writing style is exactly like that. I don't know, is anyone experiencing the same thing??
