If KF was run by someone that actually wanted it to succeed
Dunno what you mean by succeed, but if I were in Null's shoes I'd do two things; Remove posts that get complained about as he is doing with the redaction he implemented, and try to get more money.
The first thing is just because his ass WILL be on the street if he doesn't. And if that happens, he can kiss his KF tugboat goodbye. The site being up is the only way he can get money right now.
Clearly, the bottleneck in his operation is money. He doesn't work, and relies on donations. It seems clear to me that his #1 priority should be making it as easy and enticing as possible to send him money, but he does basically the opposite.
As for how to get money, I'd have more (and more varieties of) merch. Stickers, posters, etc. Whatever you can put on redbubble. I don't know how he's doing the payment for his current merch stuff and I don't really care, but the fact of the matter is that Kiwifarms has a marketable brand.
Also, have it up front and CRYSTAL CLEAR how to send me crypto. I've seen a lot of people asking "how do I turn my cash into crypto" and never seen Null help them through it. I wonder how much money he's left on the table that way.
Of course, he won't get out of his own way and continually alienates people who seemingly would give him money by being a standoffish, angry retard whenever he posts, but I think it's a lot smaller of an aspect than it would initially seem. People put up with autism when they can be paypigs, just look at any twitch streamer.
