This is definitely fake! I did some simple googling and found this : http://leakster.net/leaks/fbimail It seems someone else already did this hack and these guys simply copy-pasted the passwords to make it look like their hack. Apparently, these copy-pasters are The Hackers Army from Pakistan.
This link on Hackernews is nothing but a publicity stunt by THA. Waste of few minutes of my life.
