Who decides what is recommended to be blocked or not?
Actually, no one. There is not a single human being involved except for the programmers who maintain the systems and databases used in evaluating the data. We receive data from remote servers throughout the day that contains the server address and the score for each message the server receives. The score is a numeric representation indicating how “spammy” or “un-spammy” the message was. It is not subjective and the same basic rule sets are applied to every message regardless of where the server is located. This allows us to maintain accurate data on each server (address) reported, and apply calculations evenly and consistently and publish a recommendation based on actual statistical analysis.
