1. A computer-implemented method comprising:
calculating a quality score associated with a device identifier corresponding to at least a first user device, wherein the quality score is calculated based at least in part on (1) at least one of a plurality of evaluation rules and (2) values corresponding to at least one of a plurality of parameters associated with the first user device;
determining that the device identifier is not shared between multiple devices based on a comparison between the quality score and a predetermined threshold associated with a range of quality scores; and
based at least in part on the determination that the device identifier is not shared between the multiple devices and an electronic indication that an online session between a computer system and the first user device is likely fraudulent, adding the device identifier to a blacklist such that network traffic from devices, including the first user device, with an association to the device identifier are blocked.
