This video covers six signs of a bad therapist (or really six signs of a less-than-ideal counselor). I'm using the word counselor here not necessarily to refer to a particular professional identity, but to anybody who can deliver therapy. A professional counselor would be included in that, but also a social worker, psychologist, marriage and family therapist or some other similar profession.
It's also worth mentioning here that most counselors are good. This video is focusing a lot of negative aspects that might be seen in the world counseling, but the vast majority of counselors do a good job under a lot of different circumstances. I tried to make this list fairly objective.
#1: Not being clear about licensure status.
#2. Falsely claiming doctoral-level competence.
#3 Suggesting or engaging in a friendship or a romantic/sexual relationship with a client.
#4 Incorrect diagnosing
#5 Dogmatic loyalty to one treatment modality.
#6 Confusing art and science.
