Systems and Methods for Detecting Spam

Abstract:

In one embodiment, a method includes a social-networking system receiving requests from client devices of a plurality of users to perform user actions. The system may determine that a first user action of the user actions performed by a first user of the plurality of users is undesirable. The system may access user information associated with the first user and action information associated with the first user action. A first signature associated with the first user may be generated based on the user information and the action information. The system may compare the first signature with signatures associated with user actions performed on the social-networking system to identify a set of matching user actions. The set of matching user actions may be labeled as being undesirable. A machine-learning model may be trained using information associated with the set of matching user actions.
