From what I viewed on Kiwi Farms a while back out of curiosity, I came off with the opinion that it was paparazzi for internet celebrities ran by the worst of the 4chan users - cyberstalking, incredibly dicey jokes/senses of humor.
Even if the website is abhorrent, I wouldn't want it filtered from the internet, especially by such a large company like Hurricane Electric.
Maybe a group of people hated the site so much they've been badgering anyone and everyone possibly connected to it to block it and they've finally found an "in"?
Not sure I agree with the blocking of the website since traffic should be free-flowing irrespective of it's content in my opinion...
