Abstract: Systems and techniques are provided for managing and categorizing undesired phone calls and text messages. In a specific implementation, information indicating that an electronic communication received at a mobile communications device of each user in the crowd should belong in a specific category is received from a crowd. If a number of users in the crowd exceeds a threshold value, information identifying the electronic communication is stored in a database as belonging in the specific category. The database is provided to a mobile communications device of a user, where when the electronic communication is transmitted to the mobile communications device of the user, the electronic communication is blocked at the mobile communications device of the user because the electronic communication is in the specific category.

Abstract: Systems and methods for uploading location information based on device movement are disclosed. In some embodiments, location information may be received or determined by a mobile communications device. The location information may be associated with a physical location of the mobile communications device. A rate of movement of the mobile communications device may be identified. In some embodiments, the location information may be transmitted or uploaded from the mobile communications device to a server. The frequency of the transmitting or uploading of the location information may be based on the rate of movement of the mobile communications device.

Abstract: Systems and techniques are provided for managing and categorizing undesired phone calls and text messages. In a specific implementation, an electronic communication identified by a phone number is intercepted at a mobile communications device before the electronic communication is received by an application program on the device. The phone number is sent to a server for the server to identify a category associated with the phone number. The category is received at the mobile communication device. Based on the received category, a determination is made as to whether the application program should be allowed to receive the electronic communication. If allowed, the electronic communication is forwarded to the application program; else, the electronic communication is not forwarded.
