I unfortunately know of a woman who's claim to fame is that she was on the show. She'll tell her story regardless if you want to listen to it. Some of the brainless garbage (her included) are for real. They get fired up by the staff, that they are going to air their views, and make their statements to the public.
The other half are plants. They get scripts, or are told to make the other half look like complete fools, betray a confidence, etc. The dumbshits are often led to believe these people are on their side.
I never saw that particular episode (Actually I never watch), but that woman I met was supposedly made a complete ass of on the show.
