Who's to say this guy isn't getting what he wants -- attention.
I think he's getting plenty of it. Might be time to end the whole thing by not giving him any more attention.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
