You don't have to give away your info.  It can be hacked, bought, found and on the Internet, location is a moot point.

There's a wonderful and scary underground part of the web most don't know about and good luck finding.  It requires a browser you've never heard of which was created to be untraceable and its frustrating as hell to the government.  You know how you get suggestions from google when you try to find oh, mileage and end up with a naked chick on a huge wrecking ball?  Well, unless you know the exact words to search by, google will not allow you to find this underground market nor the browser to use it by giving suggestions.

I bring this up because while the ability to easily and covertly buy a kilo of coke, all the automatic weapons and rare animals I wanted was startling - the lists for purchase of PayPal accounts with money in them, bank accounts with PINs, CC numbers with your 3-digit number and expiry was mortifying.  And in this system, the buyer has to verify receipt and quality of goods before funds are released so those aren't canceled account numbers they're selling!

If someone wants to bankrupt you, expose you, whatever - its easier than you think.  All for sale.
