Additive friend suggestion for account security
Systems, methods, devices, instructions, and media are described for generating suggestions for connections between accounts in a social media system. One embodiment involves storing connection graph information for a plurality of user accounts, and identifying, by one or more processors of the device, a first set of connection suggestions based on a first set of suggestion metrics.

The set of connection suggestions is then communicated to a client device method associated with the first account.
