How is this a question? You're allowed to stay online because you have a dozen members on at peak times. Your userbase is growing because of people joining to talk about the Kiwi Farms. The Kiwi Farms/Null forum contains a good 50% of all posts.
What exactly is preventing you from making your own A&H forum? Why do you need to directly ask for Null's user base? And why would he NOT tell you to fuck off? If his site had been down for months and Null had given up, maybe you would be justified in making a proposal like that.
1. The daily stormer is still up. Stormfront is still up. Doxbin is still up. 4chan is still up. ED survived heroin junkie admins/owners, multiple attempts both internal and external to take it down and it is still up, 8chan is now 8kun and still exists and has a /cow/ board. Multiple sites with /i/ boards still exist and are active. PirateBay, Demonoid, and other torrent/P2P networks are still up.
Do you think KF being taken down is the rule instead of the exception? If you think that you're the dumbest, blackest, most retarded gorilla nigger I've ever met.
Josh isn't special, and neither is KF. Josh isn't the lone knight manning the boundaries of free speech. He's not Aragorn charging into Mordor yelling "FOR NET NEUTRALITY!"; there are plenty of people and plenty of sites who value free speech and don't let cocksuckers interfere with them.
2. We have an A&H board.
3. Josh is well within his right, no shit sherlock. If I were in Josh's position, I'd have already started decentralizing everything when CF dropped the site. Josh is Mister Federated Libertarian Fuck Censorship lelelelele "donate bitcoin so I can start my own bank" except when it means sharing the responsibility of hosting content.
If you can make a defensible argument against decentralizing the content to protect it by all means, but if you just want to make your own stage for people to watch you tongue-juggle Josh's balls; no one's going to listen to you.
