Do NOT go to this website! It is a phishing site to get your credentials!
Booking.com sent me to kayak.com to book airline flights. And everyone in here says it's safe, so I'm using them and allowing them in uMatrix.
I use Booking.com all the time to book hotels.
Never had a problem.
I use AutoMapper and Visual Studio pointed me to this site. So I guess it's ok.
I allowed script on this site.
Email from email@example.com saying they hijacked my account. This time they didn't try to spoof my email.
kinoi.jp might be legitimate and this guy just spoofed their domain. But I gave them a low rating because of this email.
