I've never had a FB account, but some years ago I got an email from FB listing a number of my friends and family and saying, "All these people have FB accounts. Wouldn't you like to join FB?"
The email included a reply option labeled "don't contact me again," which I chose and then replied. But a few months later I got the same invitation.
Needless to say, I found that to be deeply disturbing, and it confirmed my determination to never subscribe to FB. Later I learned about the phantom accounts. I'm sure FB maintains a dossier on me to this day.
