Are drug and alcohol counselors allowed to talk about clients on facebook?

[Not Sure]

I know of a Counselor who constantly writing on her facebook page about her clients. Just yesterday she said she met the nicest drug dealer, and then she went on to say in her comments how he is the worst kind because he is a dealer and a user.. and also how he is from Virginia. She didn't give out his name, but I think that is enough information to not be appropriate. She does this constantly, about her clients. Am I the only one who thinks this is a violation of HIPPA in some form ? I wonder if I should report her. I understand if the job is so stressful that she needs to vent, but venting and saying personal details, seems wrong to me. What do you think ? I know I wouldn't want my counselor who I trust to be talking about me in any way whatsoever, outside of the office. It just seems wrong to me, and inappropriate.
How would I report her ? Because she has been doing this for awhile, and when I talked to her about it, she said that she was not violating anything. That she blocks people from reading what she writes...... but still...... I feel its so wrong, and such a violation of trust to say anything outside of the room. It makes me sick.
