PC World notes that ID thieves are increasingly targeting MySpace users, with IM-oriented phishing attacks leading the charge. Now my two cents..
As much as I inquired about MySpace’s methods, the site can’t be held solely to blame for what is and what may happen here. When you add your name, general (or more specific) location, birthday, email, and IM address into a single database, you are looking for trouble, and only education is going to make users aware of that. Yea, its supposed to be fun getting birthday wishes from your friends – even those you haven’t heard from in a while. But from people you hardly know (and likely never have met in person)?
Not worth the risk (and I personally don’t like hearing about how old I am anymore either).
