Amazon's customer service backdoor
Whois is great for social engineering attackers. You get a name, email, address, and the first service to attack.<p>Meanwhile, the ICANN is working around the clock to make it illegal for us to protect our personal information, and whois protection is becoming an increasingly niche service for registrars.<p>For example, gandi.net (and thus Amazon) doesn't hide your name when you have it turned on. By the time you find this out, it might occur to you to just type in a different name, but now you're violating ICANN policy. And it's already been scraped by any of those whois history websites.
