I am an admin for a couple of servers that I co-admin with a few others, and one of them claims that there is/are keygenerator(s) program(s) out there that generate legitimate keys. I understand that pirated copies of the game come with a keygenerator, but that once applied the software only runs on "cracked" servers. I believe this admins claim is preposterous and that he is over his head. He also claims that you can buy one of these generators for $100. I thought I'd follow up on this anyway, no matter how outlandish it sounds. I also figured this would be the place to ask, because, as I'm sure, if someone got wind of this it would be all over the CoD4 community, especially this place.
I'd rather not go out and see if I can find one of these myself.
