Improved RDAP systems, RDAP services, and RDAP methods identify users and clients and keep track of their RDAP activities. The RDAP systems, services, and methods analyze the activities of a user (or a client) and detect or determine whether or not the user is engaging in undesirable, malicious, or otherwise abnormal activities. If so, the RDAP systems, services, and methods take action to reduce, eliminate, or otherwise mitigate the undesirable, malicious, or abnormal activities of the user.
