At the end of junk emails why is there always a lot of gibberish sentences? What are they for? Also some google searches bring up the same pages of gibberish over and over again because they have so many random words on them. I am desperately afraid they may be some sort of dreadful incantation to summon internet demons. Eg these from the most recent three junk mails:

"You will give me the cheque I ask," he replied with a snarl, "or cinema

I think they have just outsourced Spam to Mumbai. Its obviously the same people who answer calls for the UK banks and building societies.

I think it is something to do with fooling spam filters that use Bayesian algorithms.

IR35 Avoider is correct. It is an attempt to get past your spam filter by including some innocuous words other than viagra, penis extension, mortgage and brazen sluts.

[Skeptical]

and the interesting thing is that it cannot fool any decent modern filter. But I guess the spammers think that it never hurts to try.

I often get spam email that contain just one word. QUIT.

Yes QUIT, on it's own and in capitals.

Are people trying to tell me something?
