Abstract
A computer implemented method comprising receiving a list of one or more contact points from a sender and comparing the list of one or more contact points to a satellite server's do-not-contact list. Any contact point on the list of one or more contact points that appears on the satellite server's do-not-contact list is reported to the sender. The satellite server's do-not-contact list is generated from a do-not-contact list distributed by a master server. A registrant registers with the master server to provide a registrant contact point to be on the do-not-contact list to be distributed by the master server. The contact points in the registry may be organized in a hierarchy with preferences at one or more levels.
