RBLTracker supports several premium data sources, including data from the Project Honey Pot distributed decay database. Project Honey Pot is the first and only distributed system for identifying spammers and the spambots they use to scrape addresses from your website.
Project Honey Pot data is provided to all paid RBLTracker customers, and can be enabled from the Manage -> RBL Profiles section of the RBLTracker Portal.
Simply click on the name of your RBL Profile to edit it, and then select “Project Honey Pot” from the Premium Data Sources section near the bottom of the edit window.
