@Michael-Murphy, thank you for reporting this. I was actually worried people were getting that email when they shouldn't, but you're only the second first person to report it, so thank you! If thought the first person's issue was a one-off, but apparently not.
I think fixed it just now, but anyway I decided to make it an opt-in feature instead of emailing by default.
Now you'll see this checkbox in your profile, and it's unchecked by default:
