Fishtank has shown itself to be a show that is very hostile, humiliating and degrading towards women, in addition to harassment from the community.
I think there are two major problems for "normal" women to apply that don't necessarily correlate with what's on the show itself:
1. Jets behavior: Every person who isn't completely retarded will do a bit of Google research. I think Jets behavior would be a lot more excusable for some people, if he would have only ever had "relations" with fangirls as opposed to contestants. That makes it way harder to "separate the art from the artist". Even for people who don't care about the morality aspect, it might imply that you have to fuck Jet to win. I think we can all agree that this is not an appealing trajectory.
2. The fan base after the show: The tiniest bit of research will show you that you won't become a famous content creator by being on fishtank and it might actually ruin other opportunities.
Especially Tays whole stalker thing will turn off lots of women. I'm honestly impressed how Josie who had a pretty weird fan base that defeneatly crossed the line to being creepy, managed to foster a community that seems to be less insane than the regular fishtank audience. I don't think everyone would be able to handle that.
I think women are okay with being humiliated, as long as there is a feasible reason to endure it, but being on fishtank has no incentive whatsoever. After everything that has happened, I could imagine every somewhat conventionally attractive women that does well on FT, will be accused by at least some strand of the fandom, of having fucked Jet. Why would you want to do that to yourself? (IMO that's worse than having your hair cut off)
Aren't you like Australian? Also please tell me you showed your ear cartilage in the jar for your audition! (Sorry, if I'm remembering the origin of the cartilage wrong.)
I did really like the concept of bitchtank (even though I'm a Haley hater for life

), but looking back, it's really obvious that a lot of it sucked because Jet fucked several of the contestants. It becomes really obvious on a rewatch...
