would it blow your mind if I told you there are already idiosyncrasies in the way you write? not you specifically; everyone has them

I use lots of em dashes and emojis now to blend in.

Same. I no longer fix spelling mistakes (I never used auto-complete or "smart" keyboards).

I accomplish the same thing by saying "fuck" a lot. :D

Same, I've started adding stylistic (-/; with an odd/imperfect placement- like this) errors to make it clear it's artisanal home made slop, not AI-generated.
