It looks like AI can now unmask any anonymous account on the internet. That’s according to a new study by Simon Lermen (MATS), Daniel Paleka (ETH Zurich), Joshua Swanson (ETH Zurich), Michael Aerni (ETH Zurich), Nicholas Carlini (Anthropic), and Florian Tramèr (ETH Zurich), published on arXiv.In the paper, “Large-Scale Online Deanonymization with LLMs,” the researchers show that modern large language models (LLMs) can re-identify people behind pseudonymous online accounts at a scale and accuracy that far surpass previous techniques.The core contribution is an automated deanonymization pipeline powered by LLMs, according to the new study. Instead of relying on structured datasets or hand-engineered features—like earlier attacks on the Netflix Prize dataset—the system works directly on raw, unstructured text.Given posts, comments, or interview transcripts written under a pseudonym, the pipeline extracts identity-relevant signals, searches for likely matches using semantic embeddings, and then uses higher-level reasoning to verify the most promising candidates while filtering out false positives. The result is a scalable attack that mirrors—and in some cases exceeds—the effectiveness of a dedicated human investigator.To evaluate their approach, the researchers constructed three datasets with known ground truth. The first links pseudonymous Hacker News users to real-world LinkedIn profiles, relying on cross-platform clues embedded in public text. The second matches users across movie discussion communities on Reddit. The third takes a single Reddit user’s history, splits it into two time-separated profiles, and tests whether the system can reconnect them.https://www.zerohedge.com/markets/ai-can-now-unmask-anonymous-internet-users-new-study-finds
Across all three settings, LLM-based methods dramatically outperformed classical baselines, which often achieved near-zero recall.The headline numbers are striking. In some experiments, the system achieved up to 68% recall at 90% precision—meaning it correctly identified a substantial portion of targets while keeping false accusations low. Even when matching temporally split Reddit accounts separated by a year, performance remained strong. In contrast, traditional non-LLM approaches struggled to produce meaningful matches. The findings suggest that advances in reasoning and representation learning have transformed deanonymization from a niche, data-hungry attack into a broadly applicable capability.The study says that a key concern is that the attack pipeline is composed of individually benign steps: summarizing text, generating embeddings, ranking candidates, and reasoning over matches. No single component appears inherently malicious, making it difficult to detect or restrict through conventional safeguards. Moreover, the study finds that increasing model reasoning effort improves deanonymization performance, implying that as frontier models become more capable, the attack may become even more effective by default.The broader implication is that “practical obscurity”—the idea that scattered, pseudonymous posts are safe because linking them is too labor-intensive—may no longer hold.Persistent usernames, writing style, niche interests, and cross-platform references can collectively act as a fingerprint. The authors conclude that threat models for online privacy need to be reconsidered in light of LLM capabilities. While not every account can be unmasked, and performance varies by context, the study makes clear that the technical barrier to large-scale deanonymization has fallen dramatically.
>>529357066>Anonymous account Wonderful oxymoron there
>>529357066jokes on them I never type the same shit. Ai is a hoax.
>posting on social media accounts
>>529357066>according to the new studyfunded by Ai. It's like rockefeller pharma funding it's own studies to come to a predecided conclusions. Go fuck yourselves fat bastards. Ai is designed by a bunch of stupid jews that cannot create or build anything of value in the first place. Thanks for the laughs
>>529357066I purposely change my typing style on here and it's the only place on the internet i post, suck my dick and good luck fags

You realise these AI companies release these bullshit marketing stories as a way to scare the goyim into submission right?>don’t be le antisemitic goy, we are in your walls, we know what you jack off to Lol fuck off kikes. Jews can suck my dick and tongue my anus for good measure.

>>529357070This is actually not super impressive. If you're in the bottom 70th percentiles of "I post PII about myself on the internet", an AI might accuse you of being someone, and it will be wrong 10% of the time.The typical redditor isnt conspiratorial enough, but most of /pol/ I assume would be, to never disclose such details even under an anon account. At best, your industry, marital status, state... not your company or job title, not your exact age and child/pet count, not your city or reams of posts in r/(insert your town) that make it obvious you are local.That said, an AI with access to telecom data and the reddit (or, say, x.com or 4chan) db, with IP addresses and browser fingerprints? We're 99.9% identifiable by an AI, no question. I guess we will be outed by a government or sophisticated actor, while retarded x/reddit/etc. Anons will get outed from public info slightly earlier.
