Did I just scared an author ?

I feel a bit silly. I'm pretty new to AO3. Yesterday I came across a work while browsing tags. Two chapters no more and I think it was the author's only work. I read you sometimes and I thought it would be nice to leave a comment for the author, that it would be encouraging. Nothing special, I was just saying that I liked the atmosphere and that I was looking forward to reading the rest. A few hours later I went through my bookmarks and realized that the author had deleted their work. Did I scare them off? 🫠 For those of you who write, have you ever done this?
