Automatic Subtitles

The first players of Signal and Noise noticed that the first YouTube videos had automatic subtitles, created by YouTube translating the backward audio from Russian, French, and Dutch. This included references to footballer Sergio Aguero, Leslie, The Mayor, and other apparent non sequiturs.

These turned out to be completely unintentional by the gamerunners. Nevertheless, many of these phrases have become important in the story as it's gone on, as tribute to the first players of the game. This comprises a sort of roundabout player input.
