Spam, Eggs, Bacon, Sausage and Spam

It's interesting now that I am on Facebook, I am getting Facebook related spam. But not only on the email I use for Facebook, but my other email address which I keep a little more private. Alas, this email address has also fallen to the curse of spam, but not nearly as much. I just wonder if spammers have the two addresses related somehow? Perhaps Mr. BTEG knows.
