Banning IP ranges from the USA is also sketchy. Maybe banning ranges from Nigeria, or Khazakstan, makes sense. But the USA??
Oh, BTW, there is nothing sketchy about banning malicious sources of traffic. If you think botnets don't originate from the U.S. you are just wrong.
Anyway, I was just speculating about the IP Ban. I have no idea if that is the case, which is why you need to ask Kano, not in random posts.
