It is likely that there will never be a site like 4chan again—which is, likely, a very good thing. But it had also essentially already succeeded at its core project: chewing up the world and spitting it back out in its own image. Everything—from X to Facebook to YouTube—now sort of feels like 4chan. Which makes you wonder why it even needed to still exist.

"The novelty of a website devoted to shock and gore, and the rebelliousness inherent in it, dies when your opinions become the official policy of the world's five or so richest people and the government of the United States," the Onion CEO and former extremism reporter Ben Collins tells WIRED. “Like any ostensibly nihilist cultural phenomenon, it inherently dies if that phenomenon itself becomes The Man.”

My first experience with the more toxic side of the site came several years after my LOLcat all-nighter, when I was in college. I was a big Tumblr user—all my friends were on there—and for about a year or so, our corner of the platform felt like an extension of the house parties we would throw. That cozy vibe came crashing down for me when I got doxed the summer going into my senior year. Someone made a “hate blog” for me—one of the first times I felt the dark presence of an anonymous stranger’s digital ire, and posted my phone number on 4chan.

They played a prank that was popular on the site at the time, writing in a thread that my phone number was for a GameStop store that had a copy of the ultra-rare video game Battletoads. I received no less than 250 phone calls over the next 48 hours asking if I had a copy of the game.

Collins, like me, closely followed 4chan's rise in the 2010s from internet backwater to unofficial propaganda organ of the Trump administration. As he sees it, once Elon Musk bought Twitter in 2022 there was really no point to 4chan anymore. Why hide behind anonymity if a billionaire lets you post the same kind of extremist content under your real name and even pays you for it?

4chan’s “user base just moved into a bigger ballpark and started immediately impacting American life and policy," Collins says. "Twitter became 4chan, then the 4chanified Twitter became the United States government. Its usefulness as an ammo dump in the culture war was diminished when they were saying things you would now hear every day on Twitter, then six months later out of the mouths of an administration official."

But understanding how 4chan went from the home of cat memes to a true internet bogeyman requires an understanding of how the site actually worked. Its features were often overlooked amid all the conversations about the site's political influence, but I'd argue they were equally, if not more, important.
