A company in Palo Alto (Blue Security) tried to take on spammers by spamming them back.
See:

The spammers used high jacked machines (“bots”)
to bring the Blue Security web site to its knees and cry uncle.
Since most of the MS software in the 3rd world is counterfeit, the WGA updates won’t allow for the patching of these machines against the installation of malicious software (like bots and zombies).
MS admits that a great number of machines that its removal tool scans were infected with these “bots”.
So my point is that WGA is a two edged sword,
yes, it helps MS to combat piracy, but the price that the rest of the world is paying, is one of SPAM,DDOS blackmail and proliferation of virus attacks.
I am of the opinion that most of this is caused by unpatched MS software that now, because of the WGA campaign, will be even harder to combat because of the greed of the company.
