By analyzing post content and cross-referencing public data across platforms like Hacker News, LinkedIn, and Reddit, LLMs can infer personal details such as location, occupation, and interests. The process costs as little as $1–$4 per profile, making large-scale deanonymization economically viable. This threatens online pseudonymity and raises serious concerns about doxxing, stalking, and exploitation by governments or malicious actors. ## Content Recent research has highlighted a significant shift in online privacy as large language models (LLMs) demonstrate an enhanced capacity for deanonymization. The studies show that LLMs can identify pseudonymous social media users with up to 68% recall and 90% precision, which is a marked improvement over traditional methods. This breakthrough was achieved by correlating users across platforms like Hacker News, LinkedIn, and Reddit through the analysis of post content and cross-referencing public data. The method, known as ESRC (Extract, Search, Reason, Calibrate), extracts behavioral cues from unstructured text, allowing the LLMs to infer personal details such as location, occupation, and interests. These are then cross-referenced with web searches to pinpoint real identities accurately. This process, which can cost as little as $1–$4 per profile, is not only effective but also economically viable for large-scale operations. The implications of this technological advancement are profound. Pseudonymity, which has long been a pillar of internet privacy, is becoming increasingly vulnerable to AI-powered analysis. This exposes users to risks including doxxing, stalking, and detailed profiling, with potential exploitation by governments, companies, or malicious entities. As deanonymization becomes more automated and accessible, the privacy landscape for online interactions is inevitably altered, raising critical questions about user safety and ethical use of AI capabilities. ## Community discussion Top comments from developers on daily.dev. **@petermrozek** · 0 upvotes > How would have thought that a huge amount data could be used for such purposes?
