Quite apart from the ethical ins and outs of this, it's simply a buggy release. I played around with my new (and unwanted) email address and found the following: 1. Email sent to the new facebook address from the gmail account associated with my profile gets delivered to my facebook messages. 2. Email sent to the new facebook address from another gmail account I own is not delivered. It simply disappears. This is basic stuff. I guess they did like no testing before they released this f*up to their billion or so users.
