Man, the next decade only starts next year. The current decade is actually 9 yrs + 7 months old.

That makes sense because there is a financial incentive to do so:
  1. Create the ultimate spam filter: all spam goes to the junk folder with very little mistakes
  2. Sell advertising space to advertisers who want to figure in good place on a "white list", so your spam is not filtered.
  3. Profit !!!
