I've never voted it's just way too manipulated for me to have bothered. It's a show which is largely about making people into eviction fodder, about trying to create hatred beyond what would be normal. I think the HMs often know what their role is, so they are less puppets in a sense than the audience. It's the audience who are controlled more, they are the people who they take the money from and who have made the show a money spinner.
