No such thing as "private" Facebook profiles.
Sorry to break it to you.
They can be seen by anyone who really wants to see them. And not illegally, either.
As for the email address: it doesn't really matter about having separate ones, as long as your password is hard to crack. What matters is not emailing relative strangers from an account that shows your real name. Just use initials.
I've lost count of the number of people I've met online who email me from an account that shows their real name and surname. That and their hometown is enough for anyone to find out their current address online on websites such as 192.com, leaving themselves open to stalkers.
I've had several email exchanges with people on dating websites who claim to be this or that. From doing a bit of googling once they have stupidly given away their real identity, it's interesting finding out who they really are, what they really get up to on the internet, and how many lies they told in their profiles.
Their idiocy just blows me away.
