I've learnt when it comes to engaging with certain psychiatric and mental health services to keep in mind various options, allies and plans of actions. And don't follow orders. Be non-conformist. It's the only way to survive. IMO
Confidentiality is a one-sided affair for some so-called professionals. Anything goes if it's a matter of saving your own skin or following orders or keeping in with the high heid yins. It's not a matter of conscience.
Disclosing personal stuff to do with carers/survivors is OK if the end justifies the means. They can do what they like it seems and not be accountable. A slippery slope.
Posting stuff on national websites on view to the world that is inappropriate and degrading.
Locking patients in seclusion rooms and leaving them for hours on end, unobserved.
Intimidating carers by making them go to a ward back door, in the dark, icy surfaces, to visit their locked-in family member.
Getting away with it because they can.
So far anyway ...
