As the practice grew, developers created permanent plugins for popular Discord modifications like and Vencord . A prime example is the Fake Deafen plugin for Vencord. When activated via a command like /fd , it modifies the voiceStateUpdate function. In a standard scenario, toggling deafen would disable your client's audio. With the plugin active, the application lies to the server about your status while keeping your audio pipeline open.
It is getting caught.
