I think the cat is out of the bag regarding any expectation of privacy in this country, especially on the internet. Your information is readily available via local and state government records like real estate taxes, etc.
Heh, heh, from FB to Google (gmail)? Yeesh. Anything Google is flypaper as well. Yeh, I know, they don’t read your email...or the transactions surrounding the generation and/or communication thereof...or do they.
Everything you write on the internet stays on the internet, even stuff before the internet shows up on the internet. There has not been privacy for a long long time, if there actually was. When I was a kid a million years ago in a rural farming area we had party lines, everyone knew everything about everyone, our phone ring was two longs and a short (not sure why I still remember that).
You are right Grey its all out there.
