I think the related topic of "yellow flags" is also interesting. Yellow flags might or might not be ethical violations, but instead therapist actions which show he/she is not a very good therapist and that you might seriously consider terminating and seeking better help elsewhere.

Possible yellow flags (in my opinion):
--therapist does not really listen to you and forces his own agenda
--therapist is overly directive and repeatedly does not follow your lead on where to go in therapy
--therapist is inflexible and can or will not switch from a therapeutic approach that is not working for you
--therapist does not refer you to another therapist when he sees your needs are outside his scope of practice
--therapist is repeatedly insensitive and lacks empathy
--therapist seems uncomfortable talking about certain topics
--therapist is unreliable--he repeatedly cancels sessions, double books your session, is not there when you show up for session, cuts your session short, fails to return phone calls, etc.
--therapist shares your confidential information with others
