Abstract: A system for collecting, maintaining, and distributing information and preferences of workers regarding whether and how they wish to be contacted by professional recruiters (or “headhunters”). Such a system involves the workers entering identifying information (e.g., name, profession, phone number, address, etc.) and their preferences though an Internet website, email, telephone, mail, or by other method. The information is then collected into a database or pair of databases—a “whitelist” of people who wish to be contacted by professional recruiters, and a “blacklist” of people who do not wish to be contacted by recruiters. The blacklist could either be sold or distributed for free to headhunters who operate in the worker's geographic area, with instruction to the headhunter not to contact the individuals on the list. The whitelist could be sold to those same headhunters as a listing of individuals who may be interested in using the headhunters' services.
