The comment had several key words from my post so, initially, I thought it was a real comment, until I saw the name of the commenter! I don't know if a bot posted a standard form response, or if it alerted a human to my post and they posted a response, or if there are people whose job it is to sit at computers all day doing searches and manually entering spam. I'd like to think it was a bot because I'm quite fond of robots, but who knows.
Their response to yesterday's post:
Thank you spammer. I might just do that.
