strange e-mail address of user ?

[erich37]

I just have a user signing up at my page using the following e-mail.

Do you have any idea what kind of e-mail-address is this ?
It looks strange to me....

It is the facebook proxy email, in other words if the user hasn't given permission for their email to be shared so instead this proxy email gets sent to you, sending email to this would still reach the end user but if the user then removes authorisation for you site then you would lose contact with the user.
