This is all based on our personal values. A counselor might believe that it is okay to discuss about a client provided they do not disclose their name and any personal information. Ethically speaking this is wrong since they are divulging information shared in confidence. If it were ethically correct, the counselor would have sought the client's approval for them to share the information. References
