Ah yes, the old fallacy of thinking that results matter. It's such a common fallacy, though. If you'd just post a couple of great performances by yourself, you could get through to all the many people afflicted by that fallacy. What can it cost you? It needn't be a huge repertoire, just a couple of effective illustrations of your non-spork technique.
I would not hold my breath. You see, this particular individual builds his "credibility" on trashing. He trashes everybody--Wang, Kholodenko, Pletnev, Argerich, Rachmaninov (!!!), Russian school, you name it... It is like in life--the worst of professional you are--the more you trash others. Subconsciously this helps to maintain your self-esteem and makes you feel good.
Please note, that particular individual never brings any at least remotely valid evidence to support any of the "ideas", conveniently saying "my ideas require no defense".
Ironically, as an illustration of good technique that member brings a lesson of Taubmann...
To anybody who starts challenging that person, s/he immediately starts talking about "idiocy and ignorance" and personal attacking--what a proven tactics! To your request to post a recording (any recording)--starts talking about breadth of repertoire

. One can immediately see--that person speaks of music and technique as an amateur, with very little knowledge as for what technique is*.
Having said that, I would love to get surprised...

I never trust any pianist whose forearms are bigger than mine as it indicates muscle-building, a sure indicator of poor technique.Faulty_Damper
