The thing is virtually every single thing that gets presented as an "AI tell" is just "a word, punctuation mark, or pattern of presenting information more common in a training set which includes a high volume of formal writing and professional presentations than it is in the experience of people whose reading and writing is mostly limited to social media and low-effort listicle-level online 'journalism'."

So, yeah, if your target audience are the people who take those "AI tells" seriously and negatively react to them, definitely craft your writing to that audience. But also, consider if that is really your target audience...
