For better or worse, my first version of any post tends to contain quite a few typos. It usually takes a few train rides of re-reading the post and making notes of the typos, then fixing them and pushing the changes once I get home, before most of them get weeded out. So there is at least one rather low grade indicator that the writing is coming from an imperfect human brain. I also double-space between sentences which can be another low grade indicator for people who care to 'view source'.
But even so, I find myself increasingly wary that something I wrote might be mistaken for LLM output. It is a nagging worry that has slightly dampened the joy of writing. I very well understand why people have become more suspicious about LLM-generated writing. But I do hope that once things settle down perhaps in a few years, the current hair trigger suspicion will ease and that people who still handcraft their blogs will not feel a persistent sense of suspicion lingering over their work.
