I did a little search and found 5 CD-key generating programs. 2 of them had a working CD-key half the time 2 never worked and 1 worked. (It seems one of the warez Groups released too fast and their first two key generators don't work. HAHA!) Found a bunch of nfo's with cd-keys as well. Bout half of those didn't work as well.
This all just goes back to the old defense v offense question and generally speaking the people attacking have the advantage. Defense is only a time delay.
Maybe he sends the email because all the stuff he found Online didn't work.
