Know anyone else that would fit the bill besides Mirial? I don't. As a result of this article, I now know the player behind Mirial went into therapy. Ergo, violation of confidentiality.
I find your argument is flawed.
While it is possible and even likely that the reference is correct, it is not certain that the person in question is the player originally behind Mirial. Theft, deception, scamming etc. is common in EvE, and I believe it extends far beyond documented/reported cases. If one cannot be certain beyond reasonable doubt, it is unwise to make claims of professional misconduct. I'm sure you'd feel the same if it was yourself under scrutiny. That said, studies (including one I have conducted myself) have shown a dysproportionately high prevalence of mental health disorders in MMORPG users, which can be correlated with usage.
On the other hand, if you're so certain when you talk about professional misconduct, why not take it up? You can earn yourself another headline and damage somebody's career...*sarc*
As a lawyer, I operate under NDAs all the time, in addition to attorney-client confidentiality. And basically, yeah, I think this doctor was professionally irresponsible, probably even outright misconduct. EVE is a small community, and the people in EVE who have lost $17,000 dollars in an overright, social betrayal is a very small universe. Confidentiality should mean just that, not speaking in vague terms so that it gives the strong implication of a very few specific individuals.
This doctor was revealing highly incriminating patient information so he could get publicity, professional attention, more patients, and thus money. Even if the doctor wasnt aware of how small and tight-knit the EVE community is, thats really no excuse, its why you keep your mouth shut when dealing with confidential matters. I find the doctors actions pretty indefensible.
EDIT: btw, the correct standard of the burdern of proof for professional misconduct (as a tort) in the US (where this guy is practicing) is "preponderance of the evidence", "beyond a reasonable doubt" is for criminal matters....
