Instagram is teeming with these conspiracy theories, viral misinformation, and extremist memes, all daisy-chained together via a network of accounts with incredible algorithmic reach and millions of collective followers—many of whom, like Alex, are very young. These accounts intersperse TikTok videos and nostalgia memes with anti-vaccination rhetoric, conspiracy theories about George Soros and the Clinton family, and jokes about killing women, Jews, Muslims, and liberals.
