Well wait, maybe they gave up the deplatforming effort largely because it’s not as easy to deplatform an onion site as it is to harass web hosts on Twitter.
Also, wasn’t a big complaint with KF their doxxing? Even if I didn’t do any bad or illegal things, I don’t really want a bunch of trolls knowing my address.
But if you HAD done bad things and they WERE documented on KF, you might try even harder to get it shut down. And if you had plenty money and influential contacts, and no moral qualms, you might succeed. Only temporarily though.
