"That doesn't make for good TV. My feet were bleeding through my shoes for the first three weeks."

The show's creator Dave Broome and many contestants strongly deny the allegations. However, other participants have supported Hibbard or accused the show of other nefarious activities. So what's the truth? It's hard to know. Filming a reality show can be a tricky business.
