I used to be desperate for any comment on my books, so desperate that even when I knew certain comments were too well-formatted and posted too simultaneously to be from a human, I'd lie to myself and return the "kindness." I told myself I should just be grateful someone took the effort to copy and paste those comments.
But now, seeing the social feeds stuffed with those long, thoughtful, emdash-heavy comments, posted by the same account across a dozen books in under five minutes, I doubt they actually read those chapters. I can't type an emdash directly into a comment section from my phone or laptop, let alone fire them off in seconds.
I'm sorry to say that, while I still appreciate the "real" support, I'm not as eager to respond to it as I used to be. On the other hand, people who spend their time reading and typing out every letter of their thoughts are rare, true treasures. I'm grateful to them now more than ever.
