A reputation system aids in the prevention of unwanted spam or malicious communications from being sent to a mobile device, such as a cell phone. A collaborative process is used to determine ratings for a collection of source identifications of the communications. The source identifications are caller identifications (IDs) of a corresponding voice or SMS communication. A collection of opinions is maintained regarding the caller IDs. The reputation system then uses a method of making automatic predictions about the caller IDs by collecting caller ID information from many users to populate the database of maintained opinions. As such, caller IDs of users who have sent spam or malicious messages can be blocked by using collaborative information from many users, as opposed to relying on individual users to block unwanted communications.
