What are some signs that a therapist may have poor boundaries with their clients?

Struggling with fantasies of deeper connections with clients, whether sexual or parental or other intense or intimate relationships beyond psychotherapy.

Obsessing about clients outside of work hours.

Failing to mention the client in supervision/consultation, out of fear the supervisor/consultant will advise return to ordinary healthy boundaries.

Can you explain the difference between an ego, soul, mind, and consciousness?

Routinely going over the time limit with certain patients, compromising the time for the next client.

Off the top of my ancient head:

General Introduction to Boundaries from Panahi Counseling:

Billy Joel attempted suicide twice and fell into coma after affair with friend's wife - KOMO

Sense of competition with persons who are important in the client’s life.

These items can happen fleetingly, briefly, in any therapy, but if they’re frequent, it’s definitely time for the therapist to get some good, solid supervision/consultation.

Frequent phoning or texting of clients to “check up on them and make sure they’re OK.”

Ground beef sold at national grocery chain might be contaminated with E. coli, USDA warns - AL.com

Disclosing feelings, fantasies, and experiences to the client in ways not related to the work the client is engaged in.

Serious disappointment when the client cancels a session.

Session-expressed curiosities about client details not relevant to the therapy.

Eager anticipation (or anxious anticipation) of the next session in ways that distract.
