This past week, I received a request to connect on LinkedIn from a person whose name I did not recognize. This happens regularly, but in most cases I can guess a connection: the person is in a technology business, or is connected with someone else I know. This person had no obvious connection.
Then I looked more closely at the mail, and saw that the email was addressed to firstname.lastname@example.org. Then I understood, or thought I did. Somebody in our organization had used one of the Xerox Multifunction Copiers to scan a document to be emailed this person. At some later date his person had signed up for LinkedIn, and clicked on the button that allows LinkedIn to see her email address book. LinkedIn had immediately sent emails on her behalf to every address in it, whether that address belonged to a person or a machine.
I suppose that someone with time to waste could create a LinkedIn profile corresponding to the address--Steven or Susan Canning, maybe. But the minor amusement to be derived from prank doesn't seem to me to be worth the multiplication of junk emails.
