:: What is white / black list
A blacklist (or black list) is a list or register of entities who, for one reason or another, are being denied a particular privilege, service, mobility, access or recognition. As a verb, to blacklist can mean to deny someone work in a particular field, or to ostracize a person from a certain social circle. Conversely, a whitelist is a list or compilation identifying entities that are accepted, recognized, or privileged. – wikipedia
