1. A method, comprising:
detecting user activity performed using a first device associated with a first user account;
generating a first user profile associated with the first user account;
receiving a request for content from a second device associated with the first user account;
determining, based upon the request for content, a resource associated with the request for content;
analyzing a user profile database based upon the first user profile to identify a set of user profiles similar to the first user profile and associated with one or more different users than the first user profile;
generating a relevance score corresponding to a probability that a first user with the first user profile accesses the resource and associated with the request for content, the generating the relevance score based upon (i) the resource determined based upon the request for content, (ii) the set of user profiles similar to the first user profile and associated with one or more different users than the first user profile and (iii) the first user profile associated with the first user account associated with the second device from which the request for content was received; and
determining whether the request for content is fraudulent by comparing:
the relevance score corresponding to the probability that the first user with the first user profile accesses the resource, associated with the request for content and generated based upon (i) the resource determined based upon the request for content, (ii) the set of user profiles similar to the first user profile and associated with one or more different users than the first user profile and (iii) the first user profile associated with the first user account associated with the second device from which the request for content was received, with a threshold relevance,

wherein at least one of:
the resource is an internet resource corresponding to a game; or the method comprises:
receiving a second request for content from a third device; and
responsive to a determination that the second request for content is not fraudulent, transmitting a content item, associated with the second request for content, to the third device.
