Do not give your login information to Fanebook.com.
I received two e-mails from ‘email@example.com,’ which, through the glory of gMail, just showed up as “Facebook” in my inbox, informing me that a friend had left a message on my wall.
If you’ve given your password and account information to Fanebook, you might want to see if you can still log in to your account. If you can’t, make sure that other sites you use (for online banking, etc.) don’t use the same password.
