The Internet is a powerful tool.
Took me about 3 minutes.
give me an hour and $20 and I can tell you all you would ever want to know about your tax records, credit history, military service, employment, house hold income, criminal record, civil citations, not to mention the basics like current and past addresses and phone numbers.
If I wanted to really try hard I could probably get your school grades.
Kids keep this in mind when you post stuff on facebook or NS, that is all public no matter what your profile status or security is. The more you post the easier it becomes to get more info. Also do yourself a favor and don't post your birthday. Sure it is nice to get little 'happy birthday' messages from a bunch of people who don't give to shits about you, but it info you should keep private.
