I'm with you on this. I am sick and tired of people who search out and access private data (or data that SHOULD be private) as a hobby. Its a form of stalking which I've been a victim of. Just because its legal does not excuse it.
We sorely need laws to protect our privacy from individuals who are essentially peeping toms and from marketing companies that abuse our information.
I have said for 30 years that all your private data should be copyright protected.
It'll never wash. Laws require legal initiatives, and the legal system is in full (if not obvious) compliance with the enforcement mechanism, and both are tools.
Instead, it's "all your private data are belong to us."
The alternative is to confuse the shit out of them, which I hope to.
