I wonder if this has anything to do with
hotmail/msn phishing scam that I reported a week or so back about a site that seemed to have been deliberately set up to trick hotmail users into disclosing their email address and password.
I should imagine that a site like that could trick quite a few of the naive, and start building up a nice list..... and once they were in the hotmail account then it could also give details of any other passies etc stored via that account.
