Dead Internet Theory—the idea that most online traffic and content is generated by bots, not humans—was dismissed as a conspiracy just four years ago. Software engineer Adrian Krebs now presents concrete evidence from four major platforms: it is no longer theory but ongoing fact.
HackerNews restricts new accounts; AI-generated posts officially named as cause
The tech community known for high-quality discussion quietly tightened eligibility for "Show HN" submissions. The official reason: a surge of AI-generated and low-quality posts. Its guidelines now explicitly state: "Do not post AI-generated or AI-modified comments. HN is a space for human-to-human conversation."
Reddit: bot comments hidden in plain sight, faking organic recommendations
While browsing old threads, Krebs uncovered accounts with hundreds of nearly identical replies—many now deleted or hidden—clearly orchestrated to push products or websites through fake "real user" endorsements in search results.
LinkedIn: AI-generated posts flood the feed, drowning real insights
The professional network's timeline is now dominated by formulaic AI content: "leadership reflections," "gratitude Thursdays," and canned career advice. These templated posts push substantive updates out of users' view, leaving genuine professional content buried under algorithmic noise.
GitHub: bots submitting AI pull requests, bots reviewing them
The open-source platform faces a new absurdity: automated tools mass-submit Pull Requests claiming to improve code, but often introduce bugs. Even more surreal—some repository maintainers themselves may be bots. Machines code for machines, machines review machines. Human judgment is being bypassed.
What this means for crypto: on-chain identity becomes existential
The Dead Internet phenomenon hits the Web3 community hard. Discord activity, Twitter sentiment, GitHub contribution records—long treated as decentralized community health indicators—could all be bot-manufactured illusions.
This is why some crypto researchers are now seriously pushing on-chain identity: if you cannot verify whether the account on the other side is human or bot, the only trustworthy identity layer lies in immutable chain records. Krebs ends with a pointed question: "Can we go back to the old internet?" The answer, like most people's instinct: We can't.
