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

General Introduction to Boundaries from Panahi Counseling:

Obsessing about clients outside of work hours.

Serious disappointment when the client cancels a session.

Why doesn't speeding significantly decrease one’s commute time? I've done a lot of road trips and driving and have experimented by increasing speed by 10–20%, but somehow this never equates to arriving 20% sooner, even on clear roads.

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

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

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

How do you get people to follow your Quora Space?

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.

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

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

What kind of pleasure do gay men get from being bottom? The idea is very appealing to me but in practice it's quite painful.

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

Off the top of my ancient head:

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

What can be done to combat group stalking and harassment by an organized gang or society, particularly when they use universal sound weapons?

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