Same as @shadow_operative2.0. I'll occasionally go to reddit for info on some of the reality shows that I watch - mainly Gold Rush Alaska. (Yes, I know.) I saw the same threads. At this point, I'd be surprised if the sexual harassment allegations amount to anything for a couple of reasons. First, I have a hard time believing more official word wouldn't have gotten out between filming and now - lawsuits, podcast statements, boycotts. Additionally, those that remained in the contest have mentioned, multiple times, the toughness of Cheeny and how she isn't a quitter. If there was a scandal, it would seem as if they'd all clam up about it as opposed to sorta needling the three that quit. I really do think they quit because they felt miserable - physically and mentally - and decided they really couldn't win for some reason.
All this being said, I'll wholeheartedly apologize if it turns out I'm wrong.
