When they are replaced, the machines typically end up being sold out of a warehouse with all sorts of private data on them.
It could be medical records, your social security number, your tax records, or anything sensitive.
A city or state or a private business could sell their machines with your arrest records, anything having to do with a divorce, child custody, etc.
FACT: your private info is out there in the hands of someone you don't know anywhere in the world.
Pray for me.
