I have a similar issue. I tend to have a very “structured” type of writing. Say on slack or Reddit for example. Using markdown formatting. Lists with bulletpoints etc. And I tend to write long detailed explanations, sometimes too long if I am being honest.

But now I find myself adding noise and imperfections to my writing (not that it was perfect) to make it more human, which is kinda silly.

The LLMs decided to use you as the model for the pinnacle of human communication style.
