weqwewe [10]

Answer:

Efectivamente, un mal manejo de los datos del cliente por parte de la empresa tendría repercusiones legales que afectarían negativamente a la compañía. Esto es así porque un eventual mal manejo de los datos personales de los clientes implicaría una filtración de dichos datos hacia el resto del público, con lo cual los datos personales y privados de cada cliente se verían expuestos en forma pública, generando así posibles daños a estos a través de la mala utilización de dicha información por parte de terceros malintencionados.
