PC is not a form of treatment or intervention. That's very clearly stated. The mods are neither doctors nor psychologists in clinical practice here. They are not here to treat people. It's just a place for people to come and get support and connection. If we don't want to support someone telling tall tales or in the midst of psychosis, we don't have to.

We aren't here to fix people. We can't. We are faceless strangers on a website.

The moderators aren't trained or authorized to assess people's mental health here. Same with suicidal ideation, for example. People can post about feeling like they'd rather die but PC is not the place to get an intervention. That does not mean that suicidal folks can't come here for comfort, right?

You mentioned psychosis, Wishful Thinker. If someone is truly psychotic, they don't know so. And intervention only works if a person actually sees a need for it. Though PC is also not a place of intervention.
