Evolving Rule Based Contact Exchange

Methods and systems are described for managing a user's contact data which use evolving sequential sets of rules where the applicability of each set depends upon adherence or proper application of a prior set. In an embodiment, an initial set of restrictions are generated based on input from a first user, the restrictions relating to contact made by a second user to the first user. These initial restrictions are subsequently modified in response to the second user contacting the first user based on the contact made and a characteristic of the contact. The methods may apply to any form of contact between the first and second users and in an embodiment applies to contact made by the second user to a cellular telephone number belonging to the first user.
