Hey, look, an area in which MS's absurd resources and general abuse of "the system" can actually benefit not only their own users, but everybody else, too.
I'm not entirely sure that, in the grand scheme of things, spammers are more harmful to society than Microsoft, but they're annoying on such a consistent basis that I won't complain if MS decides to go after them, either.
I also find the assertion that this guy is a legit businessman outright amusing; he admits to sending 15 million e-mails a day, which if you assume he's only targeting people in the US (since that's where any legit business would be targetins sales, though in fact since he's a spammer I'm sure it's not that precicely targeted) and that about 3/4 of the US has access, then he's sent 25 spam messages per year to every internet-connected man, woman, and child in the US. Like anybody has a legit reason to send that much advertising.
The sad part is that he's close to the surface of the spam world if he actually has employees and is willing to cite figures; the real sleaze (viagra and bootleg MS software) just use bot computers to do their dirty work, and probably send out ten times his volume.
