Credit reports contain a lot of personal information. In the wrong hands, a person with bad intentions could have your social security number, your address, spouse and buying habits. They would go to your credit card accounts - with that info and have the addresses changed to a PO box of their own. That way they could charge on your accounts and with you no longer getting statements, you might not realize for while that it was happening.
So no, I want people who deal with my information to be sure I am who I say I am before giving out any info.
