" Therefore I am adding to the background noise they have to sift through to find anything useful."
There used to be a small number of people who would add meaningless drivel at the bottom of every email just to give certain spy agencies something to look at. Most of them stopped when it became clear that those agencies sometimes had trouble separating complete b0770cks from real spy chatter, and such a misunderstanding could result in either a lifelong ban on travelling to The House Of Mouse or, even less fun, a one-way trip to an extended vacation on a sub-tropical island that may or may not really exist...
Of course, being on a science-fiction mailing list and discussing things like high-energy plasma weapons and orbital mechanics can also carry a degree of, ah, "excitement"...
