If you’re going to reject something as presumptive slop because of a em dash, isn’t that confessing that your discernment is so low that there’s no reason for you to avoid the slop?
Unfortunately no, I don’t think so, because people who want to avoid wasting their time on LLM writing are likely to be quite sensitive to signals of LLM writing and potentially very quick to nope out. Generally it is (or at least feels) less costly to miss out on a random blog post than it is to ingest meaningless writing. So if there’s an early sign in your writing, someone who cares probably won’t stick around and read through to the end to evaluate based on the entirety of the post. (Unless they see other signals that it’s a high-quality post, like if other people are recommending it—in which case they will probably read it even if they think LLMs were involved in the writing.)
If I’m understanding your question correctly (it seems clearly written, but the answer seems so obvious I’m doubting myself)… yes absolutely and it’s the standard tool for doing so! That’s the basis of personal journaling, or tech blogging, or many other forms of writing.
