@adnan I didn't see their post, but I saw a reply someone sent to it later that used the same hashtag. It was clear a post wasn't visible to me. I didn't know it had anything to do with me, I was just interested in what had been written in relation to the hashtag/topic and what the reply was referring to (to make sense of that).
When I opened the thread in a private window, it showed they were "quote" posting my own post and adding their own unhelpful commentary about it.
