The End of Public Posting? Analyzing the AI Security Threat to Online Presence
Coverage of lessw-blog
A recent LessWrong post argues that the rise of advanced AI analysis tools transforms public writing from a professional asset into a significant security liability.
In a recent discussion on LessWrong, a contributor examines a provocative and increasingly relevant question: "Should you be posting on the open internet?" As artificial intelligence models become increasingly adept at pattern recognition, style emulation, and psychological profiling, the safety implications of maintaining a public corpus of text are shifting rapidly. The post argues that what was once considered a tool for networking and expression-a public digital footprint-is becoming a high-risk vector for manipulation and impersonation.
The Context: From Visibility to Vulnerability
For the past two decades, the prevailing logic of the internet has encouraged openness. "Building in public" and maintaining an active social media presence were seen as prerequisites for professional growth and community building. The security model relied largely on human limitations; while data was public, bad actors lacked the bandwidth to manually analyze every individual's history to build bespoke attack vectors. The LessWrong post suggests that the proliferation of Large Language Models (LLMs) has fundamentally broken this "security through obscurity."
The Core Argument: Weaponized Pattern Recognition
The author posits that AI changes the calculus of public sharing by enabling "continual learning" against specific individuals. Unlike human observers, an AI can ingest a person's entire history of comments, blogs, and tweets to construct a psychological profile far more detailed than what a casual observer could derive. The post warns that these systems can identify "hidden patterns"-subconscious cues in writing, specific phrasing, and argumentative tendencies-that the authors themselves may not realize they possess.
Implications for Safety and Identity
This depth of analysis introduces two primary risks highlighted in the digest:
- Hyper-Persuasion and Manipulation: By analyzing a user's values, emotional triggers, and cognitive biases over time, an AI agent could theoretically craft messages optimized to manipulate that specific individual. This moves beyond generic phishing to highly specific social engineering.
- High-Fidelity Impersonation: The risk extends to identity verification. With enough training data, an AI could mimic a user's "voice" well enough to bypass social verification checks. This facilitates scams where the AI interacts with the target's friends or colleagues, leveraging the trust established by the target's public persona.
The Retreat to the "Dark Forest"
Perhaps most significantly, the discussion challenges the future of the open web. The author suggests that the only viable defense against these automated threats may be a retreat from the public internet. This aligns with the "Dark Forest" theory of the internet, where users migrate to closed, gated, and non-scrapable communities to avoid the predatory capabilities of automated analysis. This shift would represent a major fragmentation of online discourse, moving conversations from the public square to private enclaves.
This analysis serves as a critical signal for anyone maintaining a public profile. It forces a re-evaluation of the trade-off between the benefits of visibility and the emerging costs of being machine-readable.

Key Takeaways
- AI capabilities have rendered "security through obscurity" obsolete for public posting.
- Public text data allows AI to learn hidden patterns and psychological cues for targeted manipulation.
- High-fidelity impersonation risks are increasing as models can emulate individual writing styles.
- The risks may necessitate a shift toward closed, non-scrapable online communities.
- Defending against AI-driven social engineering is becoming increasingly difficult for individuals.
