Not much is lost when a list of phone numbers and names is published... remember what happened when Paris Hilton (hotel chain rich girl and occasional TV star) had her SIdekick list published. Those who didn't want to be called changed their number quickly, and some who did want to be called such as low-rated TV personality Justin Gunn made bank collecting information... he even made a Current TV video bragging about his newfound fame.
Remember, everybody in the US House of Representatives is up for reelection right now. So, those phone numbers can be pointed at contribution-taking call centers and taken to the bank..
So, is this the first WIn10 hack or just a lazily e-mailed document?
