We 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 customers, and can be enabled from the Manage -> Monitoring Profiles section of the portal.
Simply click on the Data Sources of your Monitoring Profile to edit it, and then select “Project Honey Pot” from the Premium Sources section.
