Those full of bullshit as you call them would complain that the app is rigged or fake. Reality is the best judge of all debates. Every testable claim can be tested. The rest is moot. Audiences in these YT (and other) debates are mostly in there just to validate their worldview and see the opponent getting "owned", "destroyed", or whatever (and the majority of debaters goes for the show factor too). Those few who seek to enlarge their horizons on the other hand verify all what they've heard and separate the chaff from the wheat themselves.
