It's been stated by at least one of the best SEOs I know, who has way more information than I do that Penguin would be very difficult to reverse engineer and the info they got came from some people high up at Google.
Capitalizing "penguin" and stating any site having issues related to it is about spammy links is about as easy as it gets and people would be able to recover and reverse engineer it easily if they just listened to those type of posts.
I think it's a bit more than: PENGUIN PENALTY = You built spammy links
That's a bit too simplistic and 2005 to be difficult to reverse engineer, imo.
