Seems to me 'masochist' would be appropriate.
I mean, addressing (even reading) the 10,000th post about oil, pods, tires, carburetor cleaning, and charging system abuse, to illiterates that can't fathom the search system, must say something in and of itself.
Alternately, it would seem 'existentialist' might properly apply also.
Noun 1. existentialist - a philosopher who emphasizes freedom of choice and personal responsibility but who regards human existence in a hostile universe as unexplainable
On the other hand, 'incorrigible' also fits the intended category fairly well, in the context of:
"3. Difficult or impossible to control or manage."
