1. A computer implemented method comprising:
identifying, by a computer system, a connection between a first node and a second node; identifying, by the computer system, a first set of nodes having connections with the first node and assigned to a first plurality of node clusters identified based on a clustering algorithm; identifying, by the computer system, a second set of nodes having connections with the second node and assigned to a second plurality of node clusters identified based on the clustering algorithm, wherein the first node, the second node, the first set of nodes, and the second set of nodes have connections allowing interaction among corresponding objects of a graph maintained by an online social networking system; generating, by the computer system, a first distribution of node clusters based on the first set of nodes; generating, by the computer system, a second distribution of node clusters based on the second set of nodes; analyzing, by the computer system, the first distribution and the second distribution; generating, by the computer system, an authenticity metric for at least one of the first node and the second node based on the analyzing the first distribution and the second distribution; and deactivating, by the computer system, an account associated with at least one of the first node and the second node based on the authenticity metric. |
