摘要： A network server communicating with a plurality of user terminals over a network includes a communicator and at least one processor configured to communicate with the plurality of user terminals through the communicator. The at least one processor obtains an event history including information on user input events of each of the plurality of user terminals by communicating with each of the plurality of user terminals through the communicator, determines a macro score corresponding to each of the plurality of user terminals based on each of the event histories of the plurality of user terminals, adjusts a reference value for detecting whether a macro is used, based on the macro scores corresponding to the plurality of user terminals, and detects whether each of the plurality of user terminals uses the macro, by comparing each of the macro scores corresponding to the plurality of user terminals with the reference value.
