How Spam Works?

How it works?
Every few days I am sorting through Securitypie’s spam queue. Our anti-spam engine detects most of the spam messages but there are few that it asks one of the administrators to approve. Most of those messages are targeting a single post. Assaf’s self confession “Why I miss the Soviet Union is like a spam magnet.
Why? What is so unique about those 875 words that make it different? Could it be that the desire to see “a visionary CTO with a set of brass balls. Not a Cisco kowtowing CIO” makes the difference?
It would be interesting to see how the spammers threat this post. If you have a clue, send us a comment.
