Method and server for monitoring network user behavior

The invention discloses a method and a server for monitoring network user behavior, mainly comprising the steps of: taking an executed behavior frequency in a preset time length as a judgment reference for judging whether a verification code needs to be input or not, recording an identifier of the user into a violation list when the executed behavior frequency reaches a first threshold value, and asking the user to input a verification code for indicating legitimacy of the user when the executed behavior frequency reaches a higher second threshold value, and determining whether to respond to the behavior execution request from the user, thereby shielding the user behavior of execution through a robot method, and preventing highly active user from being incorrectly operated. When the user initiates a behavior execution request again, the network user corresponding to the identifier recorded in the violation list needs to input a verification code again for indicating legitimacy thereof, thereby ensuring the se
