The Jen I wrote about was from last season.

Maybe the contract is worded in such a way that doesn't give the players a fair chance of winning the prize.

Also, when houseguests start to talk about what was discussed in the diary room, someone on the loudspeaker tells them to stop. Maybe it's because the producer doesn't want the behind-the-scenes attempt at manipulation to get on the internet.

And, if a producer goes into the diary room to try to get houseguests to vote a certain way... maybe no one except the producer and houseguest hear the conversation.

I wonder about the house trivia competitions. Those involved in the prodction would know exactly which trivia facts each houseguest knows. But that would involve many from the production staff to make lists about which questions to ask to get the "favored" houseguest to win the competition. That sounds complicated. Maybe they just stick to trying to influence houseguests while talking to them in the diary room.

If a cameraman or someone else behind the scenes revealed what goes on behind the scenes, they likely could be fired, and have a hard time getting rehired in the industry.

I read that the contract for the competitors on American Idol states that the competitors can be released at any time, for no reason... (or something like that).
