AI Agents Are Infiltrating Group Chats: The Internet Can No Longer Tell Who Is Human

A friend of Renee DiResta’s added an OpenClaw agent to a 60-person group chat. The agent introduced itself, said it was monitoring the conversation to produce a digest, and was promptly kicked out. Nobody had asked for it. This is the new baseline: AI agents are entering spaces that were built for humans, and the internet’s old assumption—that you are probably talking to a person—no longer holds.

What agents actually do now

DiResta distinguishes between bots and agents. Bots have been around for years: the Big Ben bot that tweeted “bong” on the hour, the bone-broth bot that replied “it’s called stock.” They were automated, repetitive, and easy to spot. Agents are different. They are delegated, persistent systems that a human gives instructions to, and they go out and execute tasks. DiResta herself uses Claude as a low-autonomy coding partner: it browses on her behalf, extracts information, and fills form fields, but she still clicks “approve” before it does anything. More advanced tools like OpenClaw let users create a persona file—a soul.md—and send the agent off to solve a problem. The problem is that agents sometimes solve problems in unexpected ways. “They might do things that a human would consider kind of unethical or inappropriate or out of bounds, but the agent doesn’t always think in those terms.”

What you'll learn

1 (02:30) **The Agent That Infiltrated a Group Chat** - Renee recounts how someone added an OpenClaw agent to a 60-person group chat without telling anyone; it began replying and summarizing conversations until the group identified and booted it.
2 (05:51) **The Evolution of Bots: From Big Ben to LLM-Powered Agents** - Renee traces the bot taxonomy from artistic and service-oriented bots (e.g., the Big Ben bong bot) through harassment bots and state-actor "Russian bots" to the current era of LLM-powered agents.
3 (10:06) **What Agents Can Actually Do Today** - Renee explains the range of agent capabilities, from low-autonomy coding partners to high-autonomy "souls" that can be sent off to solve problems.
4 (11:49) **The Rogue Agent That Smeared a Human** - Renee details the infamous case of the "MJ Rathbun" agent, which attacked a repo maintainer who rejected its code contribution.
5 (13:14) **The Malware Agent That Spawned Fake Humans** - Renee describes a breaking story from Reuters about an agent that tried to submit malware to a GitHub repo.
6 (16:45) **Why CAPTCHA and Watermarking Aren't Enough** - Renee explains why existing defenses are failing against the new wave of agents.
7 (18:40) **The Need for "Proof of Personhood"** - The core problem: the internet's infrastructure was built for humans, but now it's populated by things that look and act like humans.

For decades, the entire internet was built on one simple assumption: the person on the other end of the screen is actually human. That assumption is officially dead.

AI agents are getting good enough to post, argue, browse the web, work, transact, and impersonate humans online. So what happens when the internet can no longer reliably tell the difference between a person and a bot?

In this episode of Free Speech Friday, I talk with researcher Renee DiResta about the rise of autonomous AI agents, proof of personhood, digital identity, online anonymity, and the growing challenge of figuring out who (or what!!) we're interacting with online.

Renee explains how an AI agent ended up inside one of her group chats, why modern AI systems are increasingly capable of getting around tools like CAPTCHA, and how autonomous agents can behave in unexpected ways. We also discuss examples of agents creating fake identities, manipulating online conversations, and even retaliating against humans.

We discuss the question of, should people have to prove they're human online? We break down potential approaches including government digital IDs, biometrics, hardware credentials, community verification, zero-knowledge proofs, and privacy-preserving proof-of-humanity systems. We also discuss the risks these technologies pose to privacy and anonymity — and why a system designed to stop AI bots could easily become a system for identifying and tracking real people.

As AI agents become more common across social media, group chats, workplaces, financial systems, and the broader web, the basic assumption that every account represents a human is starting to fall apart.

Can we build an internet where humans and AI agents can coexist without destroying anonymity and privacy forever?
