Threads’ link to Instagram helped the platform grow fast: 100 million users signed up in less than a week, including Nazi supporters, anti-gay extremists, and white supremacists. Media Matters previously found that these right-wing users immediately tested the platform’s content moderation limits — which Meta claimed were consistent with Instagram’s community guidelines — and posted harmful rhetoric and misinformation. Meta has allowed much of this content to remain, seemingly carving out exceptions to Instagram’s policies and even backtracking when right-wing misinformers complained that users were getting warning labels before following them, claiming that it “was an error and shouldn’t have happened.”
