Why do people ask you for your full name,address and phone number in scam emails?



This is a very good article about scams where people ask you for personal information.  The main danger here is that the person could steal your identity with the information.  A second real threat is that they can use your phone number and sign up for things that cost money with your name.  For example, dating sites can bill your phone number if you don't read the fine print about functions that dating sites offer.  Someone who has your phone number, name, and address could do the same thing.  Also, they could call you and pretend to be your bank and rip off your bank account with information you might give them.
