Again, you do not know what rigging is. The clear cut definition, for this particular show, of what is considered rigging is if they script the OUTCOME OF THE GAME to whether or not they win or lose. The advice given by an audience DOES NOT MATTER to what goes on with a contestant on stage. It is still in the hands of the contestant what decision they make on stage. What the audience does is completely irrelevant.
Tell Voltron that. Tell him that, on the basis of how he's been treated the last several times he's been to the show.
What you are saying here is categorically false, or this situation would never have happened -- there'd be no perceived unfair advantage.
And, as far as that goes, you can rig a game for certain contestants to win, or for all contestants to lose. (Now, sometimes, best laid plans of mice and men, blah blah blah... Look at pro wrestling and it's history if you don't believe that to be possible.) What I'm saying (especially with this show in the hands of one of the greatest production-scam artists (Fremantle, with American Idol) in recent American history) is that I don't trust Fremantle not to tamper with the results, and see this as going down that road.
You cannot silence one person on the basis of that they do know their stuff and that people around them do as well (unless you wish to accuse that person of arranging a split of prizes should any of the people so contacted get on the show -- but that's a separate issue...) without silencing the rest -- unless you wish to mislead, deceive, and potentially screw over the contestant.
Any action by the producers which disallows a legal act from taking place with respect to gameplay alters the result of the game or has potential to do so. That's enough to at least start down the road to a rigged program.
Look at it this way: quiz shows of the 1950s got in trouble for giving the contestants the questions and the answers in advance, telling them how to act, when to pat their forehead, etc. THAT is rigging. Simply sending someone who is obviously in cahoots with a lot of audience members at previous shows to the back of the audience and said person was asked by the producers to stop giving advice is NOT rigging the show. The budget issue is secondary to all of this.
I disagree completely, but since we are at lager-heads here, we're basically going to have to disagree.
