Sorry, I didn't grasp that context from your comment. Since employees are "normal" Facebook users like everyone else, we were also subject to having vanity@facebook.com added to our profiles, and I for one immediately replaced it with my personal email address, just like anyone else can do. By contrast, our @fb.com address is our "official" account that goes to a standard email client, and has no relation to our actual Facebook profile. Some of us (including me) still prefer to use our personal email address for anything not directly related to work topics. And for what it's worth, I can vouch for the authenticity of the FBSerkan account on Reddit.
