Recent advancements in artificial intelligence have significantly improved the ability of large language models (LLMs) to unmask anonymous and pseudonymous online users with surprising accuracy. Studies indicate that these AI tools can identify social media users and link fake online names to real identities in just minutes, raising concerns about the future of online anonymity. For a minimal cost, AI can deanonymize internet users based on their comments, which has led to fears that anonymity on the internet is becoming a thing of the past. As AI continues to evolve, the implications for privacy and online identity remain profound.
