All should keep this in mind, PRIVACY IS A MYTH. In our connected, electronic world any information anyone wants about you is available for a price or free in many cases. The easiest defense is a telephone that displays the caller and receives messages. Do not answer any calls from unknown callers. They'll leave a message if they really want you.
The so-called do not call list only applies to blind calls. Does not apply if you have a business relationship with a caller and if you're a member you have a business relationship.
Lastly, I wish this was the most important thing I had to worry about.
