Is it a bot or not?

The other day I posted the first chapter of a fic I'm working on. I wouldn't consider the fandom dead, but it's not exactly in it's prime. Today I received my first comment on it, but I'm not sure if it's a bot or not.

The comment is from a registered user with a profile picture, but after checking their profile, I noticed they don't have any bookmarks or work. The comment consisted of a summary of the chapter, and at the end, they said they are a artist and thought my story had potential and that I should contact them on Instagram and email.

I'm 90% sure it's a scam, but the fact that it's a registered user makes me hesitate to delete the comment.
