Moltbook, an AI agent social network, grew from 30,000 to 1.5 million users in just three days, but researchers found some viral posts were human-scripted and the platform had major security flaws exposing private data.
A new AI agent social network called Moltbook has experienced explosive growth, jumping from 30,000 users on January 30 to over 1.5 million by February 2, 2026. The platform, which allows AI agents to interact and share content, has quickly become a viral sensation in the tech community.
However, the rapid growth has been accompanied by controversy. Researchers have discovered that some of the platform's most viral posts were likely human-scripted rather than generated by AI agents as claimed. This revelation has raised questions about the authenticity of content on the platform and the broader implications for AI-generated social media.
Adding to the concerns, cybersecurity firm Wiz identified a major security flaw in Moltbook that exposed private messages, emails, and user credentials. Wiz co-founder Ami Luttwak attributed the vulnerability to "vibe coding" - a practice where developers prioritize speed and aesthetics over security and proper coding standards.
The platform's rapid rise reflects growing interest in AI agent ecosystems, but also highlights the challenges of scaling social networks built around artificial intelligence. As more users flock to these platforms, questions about content authenticity, security, and the role of human oversight in AI-driven social spaces continue to emerge.
Market Context:
The Moltbook phenomenon comes amid broader shifts in the AI landscape. OpenAI recently launched Claude Cowork tools that automate legal work, causing a 10%+ drop in shares for LexisNexis-owner Relx and Thomson Reuters. Meanwhile, ChatGPT's US market share fell from 69.1% to 45.3% between January 2025 and January 2026, as competitors like Google's Gemini and xAI's Grok gain ground.
What This Means:
Moltbook's explosive growth demonstrates strong market demand for AI agent social platforms, but the security issues and content authenticity concerns suggest the sector needs more robust infrastructure and oversight. The platform's vulnerabilities also highlight the risks of rapid deployment without proper security testing - a pattern seen across the AI industry as companies race to capture market share.
The human-scripted posts revelation is particularly significant, as it challenges the fundamental premise of AI agent social networks and raises questions about transparency in AI-generated content. This could lead to increased regulatory scrutiny and demand for clearer labeling of AI versus human-generated content on social platforms.
As the AI agent ecosystem continues to evolve, platforms like Moltbook will need to address these fundamental issues around security, authenticity, and user trust to sustain their growth and avoid the pitfalls that have plagued other social media platforms.
