Identifying user profiles to evaluate against policies enforced by an online system based on connections between content items, user profiles, and objects maintained by the online system
An online system reviews various user profiles for compliance with policies enforced by the online system. However, users may attempt to subvert action by the online system by creating additional user profiles for presenting content. Accordingly, the online system generates a graph identifying connections user profiles, content items associated with the user profiles, and objects identified by the content items. User profiles, content items, or objects previously identified to have violated one or more policies enforced by the online system are identified via the graph. The online system computes a profile score for various user profiles based on a probability of reaching an object, user profile, or content item identified as violating a policy through a random walk in the graph. Based on the profile scores, the online system trains to identify user profiles for review against one or more enforced policies.
