You folks are entering a quagmire. The censor can enforce something but most importantly is what YOU can do. The censor gives a recommendation that such and such programmes should not be available to kids without the presence of an adult so it's up to the adult to enforce it by whatever means available - an app PIN, unsubscribing from the service, curfew for kids, etc.
The censor doesn't have to be in everyone's lifes every moment to say over your shoulder "You are not allowed to do that". The censor can recommend and the person in transgression then should bear the consequences.
Netflix and other services provide technology to prevent kids accessing such content. Parents provide the framework for kids to understand why this is in place.
Deal with it.
