Paul B. I can clearly understand you on locking doors and keeping Email and such private.
I have the same problem in someways, I do not feel banks, insurance co. and the like should be allowed to share our personal information with anyone, even another company that is part of the same family.
Here in CA they are spending millions to fight a bill to prevent that right now and are winning.
I hate junk mail, I hate spam and make it a policy of never buying from any company that sends that junk to me. I just delete it and be done with them.
To reply even to say unscribe is telling them "hey I am here so spread the word and my Email to all". That is exactly what they want to do, it translates to $$$$.
Can go on and on but one thing I never do is us my SS number as an ID, I don't even give it out to my bank on the phone. Never on the Internet.
