let's see, 70% of 2 million is 1,400,000 spam emails per second.
24 hours = 86,400 seconds.
That comes out to 120,960,000,000 spam mails daily.
Divided by the 4.5 million = 26,880 sales per day.

yea, I could see living out of a mobile trailer and staying one step ahead of the law for thousands of dollars of income daily.
