Kiwifarms, I would assume. You’ll see why if you check out their Wikipedia article.

Woosh, that went right over my head. Yes, I've read of that unsavoury place.

Well, their Wikipedia article is biased and somewhat counterfactual, as they always are whenever they possibly could be. Kiwi Farms only loosely moderates non-illegal speech, so there are edgelords dropping slurs, yes, but that there are no less than two subforums clowning on Nick Fuentes/America First and related entities should put to rest the whole "alt-right/white supremacist" narrative. Also, there is a dearth of verifiable evidence that the suicide of Near/byuu recently attributed to KF and its admin actually happened - it looks an awful lot like this guy just decided to disappear from the internet for a while (as he has done before) and found a vulnerable scapegoat to help with that.

Go to the forums, do some searches to find threads on topics that interest you, and make your own decisions.

I don’t know, there’s a ton of horrific bullying every time I stumble upon the site. I think you’re downplaying it. And loads of less-than-legal activities, like sharing videos of former porn actresses purely because they’ve tried to scrub their old content from the internet (copyright infringement), revenge porn, etc.

Just as the edgy comments are their “right to free speech”, I think it’s completely fine for XenForo to exercise their right to speech by not providing them service. It’s not like they’ve had their license revoked; they just cannot get support or software updates past when their license expires.
