MS phishing blacklist makes me wonder

As part of its anti-phishing romp (deemed suitable only for US customers, of course), Microsoft is going to be blacklisting websites deemed shady. Which brings up an interesting question – how is such a nice gesture going to be implemented?

If Microsoft stores all these sites themselves, then you have to call on Microsoft every time you surf. Which means Microsoft gets a nice little picture of all your browsing habits, whether you go to check your VISA bill or arbitrarily hit “” If the boys in Redmond pass the blacklist on to you, refreshing every time a new scam site pops up on the list (which is about once every tenth of a millisecond), then you are going to need a bigger hard drive.
