Thanks for the answer. The problem is that I really need a valid email
address, because in my site I use that email to send important
notifications to the user.
I already tried with "facebook mail", that is, joining the user name with "@
facebook.com". But it didn't work. When I send an email to a facebook mail,
I receive an automatic response from Facebook saying that there is a
permission problem. I understand that @facebook email addresses are only
for communication between Facebook users :/
