You might want to check your Timeline, and make sure that your listed email address(s) is the one you actually use. Without warning, or apparent reason outside of possibly trying to force Facebook e-mail adoption, the social networking giant altered many users’ profiles to display the Facebook e-mail address they’ve never used, which redirect to a user’s inbox and chat functionality. The company has not released any information on the change, and has yet to acknowledge what happened. Either way, now might be a good time to review the information you have posted, particularly if you run a business or want to ensure your privacy. source
Wrong, Facebook! My email address is not email@example.com. I have enough email addresses, and I don’t want another one from you.
Next they’re going to pick a new phone number for me that goes to their call centre so they can screen my calls and decide who I want to speak to. Heck - you guys decide on who my friends are too, while you’re at it.
