Something about the original comment really bothered me. And I can't quite put my finger on it. I'm not a good enough writer to flesh out what bothered me without responding to the tone.
I do feel pretty strongly that it's wrong to casually talk about mentally ill people as objects of fascination. And then to advise against engaging them because it might be a liability to yourself, as if that's the only concern. e.g.: "...[if they happen] to commit suicide a week later and mention you in the note."
I think I'm perceiving a lack of empathy in the linked article and the top comment. Or something. I think I just need to stop commenting.
