Facebook has changed everyone's default email address to a facebook.com address on their facebook profile.
The prpblem with this is if anyone sends you an email to that address it will automatically publish the email to your timeline. Which makes a protection private email public and everyone on your friend list can see the email.
Here is a step by set guide on how to fix your facebook.com default email address:
So, how do you reclaim your personal email? The process is simple, just follow these steps:
Firstly, on your personal profile, click on Update Info below and to the right of your cover photo:
Next, locate the Contact Info box:
You will note that it shows my facebook.com email address
Click on Edit and it shows your email addresses:
You will see that the facebook.com email address has an open circle to the right of it, whereas my other email addresses have a line through the circle. This means that the facebook.com address shows on Timeline, the others are hidden.
On the pull-down arrows next to the circle, select “Hidden from Timeline” next to the facebook.com address
and then against the email address you want to show publicly, select “Shown on Timeline”:
Click “Save Changes” and you’re done.
If an outside agency intercepted your private email in what is called in hacking circles a “Man In The Middle” attack it would be viewed as criminal behaviour. Let’s be generous to Facebook and say that this move comes from arrogance rather than malign intent – but now that they are a public company they have institutional investors to worry about, and it’s unlikely that those investors will be too happy with Mark Zuckerberg over this bad publicity. Maybe they will learn a lesson from here on?
