I don't think people realise that they too could set up as one of these things and charge for their services.
It's not enough to say to check for BACP (British Association for Counselling and Psychotherapy) membership, because people shouldn't have to verify that their practitioner is actually qualified. Virtually nobody seeks out mental health support when they're feeling good. And the act of seeking help in itself often makes someone additionally vulnerable.
If I have 3 months of lingering stomach pain I go to the GP. I don't have to check through websites of people who call themselves doctors to see if they've had any training, check what that training actually is, and are registered with a body I've never heard of.
AIBU to think that for the mental health/safety of those seeking help, there should be clear naming of professions within mental health and it should be a crime to call yourself and offer services in something you're not. It should also be clear what the competencies of each professional level are - and are not - so people know what they need to look for in the first place, as well as whether their practitioner is being unethical by offering something out with their training.
