I get a lot of strange email, most of which is what you would call SPAM, yet I don't understand why I get it.

Why is someone spending the time and money to send me literally hundreds of these per week, no links, no discernible purpose.

Here are some examples:

1) (arabic string replaced)

What is that and what does it mean, do I need the CIO code book or is it some type of Al Quida pass through? Anyone know?

2) oscillations Constance nonperishable fiddles

I don't have a clue what this means, nonperishable fiddles?

3) bus international Pickford?reticles crickets impressible levity unanimous

Is this a multiword Anagram with special Google algorithm meaning designed to improve rankings and SEO results?

4) baselines configuring brambly gunshot braves doubt.dualities sacrifices pawnshop awkwardness prurient overlooked oppositely poetries

I know, I know, I must have too much time on my hands, I just like to understand and figure things out, there must be a purpose, anyone got a clue?
