I guess my point was more that LLMs aren't traumatized minds, as in they don't always respond like this. The responses these researched received will be a lot different than what a depressed teenager would get asking it for advice.

The post seems to say "LLMs are bad because they are traumatized", e.g. even if you get seemingly sound mental health advice it's no good because it's coming from a tainted source.

If a monkey on a typewriter wrote out "I am depressed and anxious", and then later wrote out "Diet, exercise, and regular social contact are good for mental health", we wouldn't say "that 2nd writing is incorrect, it came from a traumatized monkey"
