Arguably speaking, maybe he does. It seems to validate the persona that he has created here, in that he is on the delivery end of the couch versus the business end.
But it's the internet, actual intervention is not possible and engaging someone in this condition just feeds the problem. I pray that posts of this nature are not made by someone in complete isolation, at least not yet, and they will listen to someone nearby when they, too, advise: "Seek help."
Until then, not engaging, ignoring, definitely not commending these kinds of posts, is IMHO, the best that can be done here.
