¿Ves esa cuenta con el icono de Android y sin nombre? Es una cuenta llamada "NothingToSeeHere", ¿alguien sabe qué puede ser y cómo puedo comprobarlo?

Lo desactivé y ahora no puedo activarlo pero sigue estando en la página "Añadir cuenta". Aunque no puedo hacer clic en él para mostrarle el nombre, "NothingToSeeHere".

Aquí está el volcado (con datos sensibles censurados) de la cuenta sysdump:
