Spammers of Dune?

I've gotten excerpts of classical literature as bodies of spam before, but this is a first:

Subject: Sense the spirit of real life with Soft Cialis
"When a sandworm had come to devour him, Selim discovered the secret of how to ride the creature. Shai-Hulud had taken him far from the Zensunni village and deposited him near an abandoned botanical testing station, where he'd found food, water, and tools. There, Selim had time to look inside himself, to understand his true mission. "

Now, if there were ever a product tie-in that Brian Herbert was going to try to make a quick buck of, it's impotence drugs + giant sandworms.

(I do feel dirty that I recognized that from one of the prequels).
