Survivor?

Just watched another episode of Survivor, there're two contestants who didn't put in effort in the challenge just because it's their strategy to make sure that they lose and their tribe could go to tribal council to vote someone out. Personally, I couldn't accept that because it's such a ridiculous way to lose, although it's just a game and it's part of their strategies to make sure they stay in the game as long as possible. Anyway, it's just a game. After all, that's why this reality show is named 'Survivor'. However, hopefully in real life, no one would think of giving up this way and become a loser without even trying hard enough or simply giving up 'purposely'.
