Seems like the most "successful" people post-tank (Josie, Mizzy, arguably Letty and Taylor) had to immediately monkey branch out of the sphere or farm up their own new audiences (while maybe keeping a FT whale or two) and even then it doesn't seem like much more than min wage earnings. Any others gotta do it for love of the game/attention farming/sharing thoughts on newer seasons/parasocial to their audience of 8 people.
Idk each season I read people elsewhere telling contestants they could totally for realsies easily make it streaming and it is so out of touch with reality, like the kids putting "Youtuber" as a dream career. Fishtank is flash in the pan attention, 15 mins of fame type shit.
