I found that one of my friends in facebook get spammed from a website its domain faceilbook.com. It links you to the real facebook sign in page in order to steal your password. Then from your account it writes in your friend’s wall something like this:
“Somebody wrote something really funny in their blog about you . everybody see it here http://leolafiker.blogspot.com”
After that link redirect them to the same domain so take care and check the URL before you sign in.
