The post discusses a technique of embedding data within emojis, which raises questions about digital secrecy and security. Users experimented with various language models (LLMs) to decode the data embedded in emoji strings, with varying success in accuracy. This method could potentially allow for the creation of deceptive links that visually appear the same yet lead to different resources. There's also mention of watermarking text, indicating possibilities for tracking outputs from models. Overall, this may change how users perceive and interact with links they encounter in digital communications.
