On Twitter, self-appointed mobs of the morally righteous call for violence against children [0], farm lulz from the killings of police officers [1], dox strangers to get them fired over off-color jokes [2], and endlessly harass and threaten certain conservative journalists and activists [3]. Actual Twitter employees harassed right-wing reporter Andy Ngo [4] after a real-world mob attack sent him to the ER with a brain hemmorhage, an event which "ACAB Twitter" continues to celebrate and remind him about.
The trolls on Twitter blend in by being a few medium-sized fish in the ocean. The trolls on Kiwi Farms are more visible as big fish in their own small pond. They're ideologically flipped compared to Twitter trolls, but fundamentally alike in their methods, moral posturing, and disregard for basic human decency. They're all an enormous net-negative for humanity.

Sounds a lot like Twitter.
