I think there is a need for the AI counseling use case, but it should not be provided by a general purpose AI assistant. It should be designed by professional psychologists and therapists, with greater safeguards like human check-ins to make sure users get the help they need.

The best way to stop this is to make those safeguards stronger and completely shut down the chat to refer users to seek help from a better service. Unfortunately those services don't really exist yet.

There would be false positives and that'll be annoying, but I think it's worth it to deal with some annoyance to ensure that general purpose AI assistants are not used for counseling people in a vulnerable mental state. They are not aligned to do that and they can easily be misaligned.
