[UA] Spam?

[Rich Harkrader]

Heyo,

Does anyone know what the heck those blocks of random text at the end of
some spam messages are for?  I sometimes read through my spam messages, and
have started to notice these.  Some are tremendously bizarre, like this one:

Something to think about: Kill chair, say along the conflict, step Haunting,
living, exposing, spilling, seducing, The king lifts, as if the key is a
suit. Ethereal the speech laughed a swell queen, joyfully Sick key as a tree
ponders about the heavy acorn, Alas, the speech has revolved quite quietly,
uncovering Yelled by glances, spills the glass to shame. Upon ancient sheep,
demonstrate not yet go concisely The futon conducts, as if the heap is a
table. Hit signs with no elongated pie.

Anyone considered if some secret message is contained within these blocks?
It seems all you'd need is the right key to decode the message.  Might be a
pretty interesting way for people in the Occult Underground to keep in
touch.  Hiding in plain sight and all.

Rich;)
