‘Kill’ your e-mail address

Four years ago, Facebook gave all of its users an @facebook.com e-mail address that would allow people to send messages to the Facebook inbox from Outlook, Gmail, Hotmail, etc.
Two years ago, the big blue social networking giant tried to force all their users to actually use it. This year, after buying private messaging service WhatsApp, they announced that they were kind of killing it: The facebook.com e-mail address would no longer send messages to your Facebook inbox, but would instead forward messages sent to it to your primary e-mail.
At the time, the company said it would eventually offer users a way to opt out of having an e-mail address that no one ever wanted be a gateway to their real e-mail inbox.
Recently, someone started using my facebook.com address — which is easily discoverable by pairing the “public user name” contained in the URL of every Facebook profile with @facebook.com — to sign up for an inappropriately-named Instagram account.
Those registration e-mails came bouncing into my real e-mail account, spam-style. Uninterested in such services, I decided to go and see if Facebook had given us the option to turn off their forwarding service. It is, of course, a little tricky to find but it’s there. If you want to kill the Facebook e-mail forwarding, read the instructions.
