Are These overly positive comments a scam on YouTube

My YouTube channel is starting to take off. As a result, I’m starting to get more subscribers and comments. This subscriber started giving me positive comments, but now she is commenting two or three times a day with these kinds of overly positive comments. Has anyone ever seen anything like this before? I have stopped replying to them, but I’m wondering if I should do anything else. It seems like doing nothing should be OK. What do you think?
