It's not just godaddy - yesterday I renewed/purchased several domains from network solutions, today a dozen calls or emails like this... you have to wonder if this is just another way to get you to purchase "private listing" for your domains...
I've noticed a pattern that when I get a website domain name through godaddy that is not registered private, a few days later I get bombarded by calls like this. Way to check on who you sell customer data to f-ers. This is the 5th call today from robo-loosers. Of course I don't pick up. Of course I block the number. Of course they continue to call on different lines.
