One or more computing devices, systems, and/or methods are provided. A request for content associated with a device and/or a set of request information associated with the request for content may be received. A content item may be transmitted to the device. A set of client information associated with the device may be received. The set of client information may be analyzed to determine a fraudulence label associated with the request for content. Fraud detection information generated based upon the set of request information, the set of client information and/or the fraudulence label may be stored in a fraud detection database. A second request for content associated with a second device and/or a second set of request information associated with the second request for content may be received. A second fraudulence label may be determined based upon the second set of request information and/or the fraud detection database.

Identifying fraudulent requests for content

One or more computing devices, systems, and/or methods for determining thresholds are provided. For example, first activity associated with a plurality of client devices may be detected. A first activity distribution associated with the plurality of client devices may be determined based upon the first activity. A plurality of peaks of the first activity distribution may be identified. A plurality of gradients associated with pairs of peaks of the plurality of peaks may be determined. A target peak of the plurality of peaks may be determined based upon the plurality of gradients. A threshold amount of activity associated with the first activity may be determined based upon the target peak. A first set of activity associated with a first client device may be detected. A fraudulence label associated with the first client device may be determined based upon the first set of activity and/or the threshold amount of activity.
