But,, Kellee said she did NOT want production to step in. If she had said, "yes' to the production member's question and TPTB failed to step in, then I would agree they failed.
But, without a complaint, there is effectively no actionable harassment. A lot of touching goes on at camp in Survivor, much more than in the real world. Most of it is consensual. Much of Dan's obviously wasn't. But, unless a person being touched is willing to step up and say they want action taken, TPTB really aren't in a position to take strong action.
Imagine if they had ejected Dan against Kellee's wishes, and there was either backlash against her, or her alliance lost the numbers advantage and she got voted out. Then, people would be saying TPTB screwed Kellee and treated her like a child, instead of a grown woman, by ejecting Dan, when she wanted to handle the situation in a way that was more advantageous to her game.
All the lying, exaggerating and downplaying by Missy and Elizabeth also clouded the issue a great deal. TPTB saw one woman complaining about the touching, but not wanting him ejected and two others telling different stories to different people to manipulate them for gain in the game. They have no formal complaint and in fact the victim expressly declined to make a formal complaint.
As I have said before, I think women (and men) should be strongly empowered to protect themselves from sexual harassment. Complaints should be taken seriously and investigated and where there is evidence strong action (like firing or ejection from Survivor) should be taken.
But, if women choose to be pragmatic (Kellee), cynical or downright devious (Missy and Elizabeth) in how they deal with unwanted touching, I think TPTB have their hands tied. Women need to stand firmly (like Janet) against this behavior and when they do, those in authority should back them in the strongest way.
