A clinical psychologist in a EU country looked at Lorien Psychology and said that the writing looked like typical American biomedical psychiatry with some self-promotion. In the UK and EU you can find psychiatrists who say things like "psychiatric diagnoses are scientifically worthless as tools to identify discrete mental health disorders," I think Scott Alexander blogged about Thomas Szasz at some point https://www.sciencedaily.com/releases/2019/07/190708131152.htm
I am not comfortable exploring the question "did he violate professional ethics?" further because that seems like an unhealthy parasocial relationship like cyberstalking or swatting. I never met him or anyone who met him. More shoeleather reporting on these communities would help!
