Repeat offenders

Yes, I think there definitely is repeat offenders, but I do not think that they can be classified as professional actors or actresses. I annoys me how the same players get asked to come back for a second chance on shows. Like in survivor, multiple players gets asked to come back. I think it dumb. They got their chance and already got to experience the show. They are taking up someone else's spot thats never experienced the show. This also happened in the Amazing Race. There are so many other people who want to get a chance to run the race, but they decide to invite people back that have already ran it and lost!
