I don't understand
A year ago I registered a domain and was to mean (and stupid) to pay extra for privacy. Since then I have been plagued by offers of web development, logo and picture services both by phone and email. A year later the phone calls have stopped and I only get one email per day now. If I had paid extra then presumably this would not have happened and my personal information would not have been exposed/sold. So a mechanism already exists to preserve privacy, albeit a paid one. So just turn it on for everyone and the problem goes away. What is this two years of development?
