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

Obsessing about clients outside of work hours.

General Introduction to Boundaries from Panahi Counseling:

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

What would have happened if Shin was a good movie instead of a bad one?

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

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

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.

Have you ever answered your door in lingerie?

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

Serious disappointment when the client cancels a session.

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

How can you tell if someone or someone's is trying to recruit or at least test you for a secret organization?

Off the top of my ancient head:

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

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

We white women don't like white men. Do you have any issue with that?

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