1. A method performed by an Internet Protocol Multimedia Subsystem, IMS, node, for handling a setup of a session between a first User Equipment, UE, and a second UE, in a communications network, the method comprising:
receiving a request to setup a session from the first UE to the second UE, wherein the request indicates a privacy value which the first UE has requested to apply for the session, wherein the privacy value indicates a level of privacy or a function of privacy comprising one or more of header privacy, session privacy, or non-privacy,
sending a request to a server node, which request comprises an identity of the first UE and the privacy value, and which request requests the server node to analyze a reputation of the first UE based on the identity of the first UE and the privacy value,
receiving a response from the server node, which response indicates the analyzed reputation of the first UE, and
deciding how to handle the session setup and session privacy, based on the analyzed reputation of the first UE.
