Surprised they're taking this route with how season two turned out with fans. A large part of the enjoyment of Fishtank is the Fish being completely unaware of the environment they've been put in and watching them slowly realize and possibly adapt. You can see the real them, which makes every action they perform a reflection of themselves. You will not get that with fans, as fans by definition are aware.
This has been discussed time and time again in this thread, but the moment a Fish becomes aware of how the audience views them, they change and will overexaggerate or underplay certain personality traits to gain favor, not realizing that these personality traits were so effective to begin with because were unfiltered.
The only time Fish have been top tier content makers while simultaneously knowing about the show is if they have some mental issue that prevents them from holding back or revealing their true selves in front of thousands of people. Some examples from season two would be Jimmy and Cole. Jimmy knew, but he's so fucked in the head by mormon rape he doesn't care about how cringe he comes off, and acts like his true self. Cole was a narcissist and autistic, his ego made him feel like he was the only Fish who truly understood the audience, so he felt like he could open up with them.
Season three post reveal examples would be Burt and Alex. Alex has junkie brain and is retarded, so you could tell him a million times about the nature of the show and he still would fall for Production gaslights. Burt is a literal schizo, and could be told the true nature of the show one million times. It wouldn't matter, he would still think it was some massive conspiracy. Both of these Fish showed their true selves because they are mentally ill.
That's not even mentioning how ineffective some Production go-to's become. Introducing old freeloaders wouldn't be a kind of unique experience where we can gauge how new contestants react to old faces, but it is instead a fan soyout moment. Sam breaking shit loses a layer of enjoyment when we know the Fish are in on the joke. Reused challenges lose their potency and shock value as well. Gaslights will not work. They might get lucky and find a retard or two, but soon that luck will run out and we'll be stuck with a late season 2/late season 3 cast for an entire season.
It will be Goranian, and long bouts of Goranian content can drive a man to insanity.
Edit: Just realized that the "audience" will determine who gets cut and who stays. It will be a season of contestants chosen by paypigs.
