You could still argue that Kiwifarms still "enables" people who are even worse than them, in the same way that certain glossy magazines enable harassment of various celebrities. Certainly Kiwifarms themselves get worked up over people who merely "enable" bad things, so they don't have that much non-hypocritical leg to stand on. Still, we used to defended those magazines for free speech reasons, and for the sake of the few times they reveal something genuinely in the public interest.
(The "credible bomb threats" was IMO not very credible, it was a fresh account claiming to be able to commandeer out Irish paramilitaries to bomb multiple sites in minutes. And the post was reported instantly, and removed within minutes. That's something that could happen to all sites that allow public comments.)
