Slight theory: did they skip 4733D because they thought the rickshaw as the 1st IUFB was offensive? Granted, some of Bob's comments that they have aired aren't exactly squeaky-clean, either...
Just watched the episode as it was posted here. I wasn't sure if the rickshaw would do it. Then when I saw the oriental rug come up as a prize, I said A-HA, that's it. I guarantee you the episode was skipped because of the oriental rug. I expect Fremantle will ban any episodes offering an oriental rug from airing as fast as Bob Barker banned the episodes with fur coats.
Although it may not make sense to a lot of people, the term "oriental" has become controversial enough that in 2016 a federal law was passed to ban the term from being used in any form by the government. See the quote:
"[Oriental] is an insulting term that needed to be removed from the books, and I am extremely pleased that my legislation to do that is now the law of the land,” Meng said in a statement."
In my research to understand the controversy around this term when I saw Buzzr was blocking it, it appeared that some people considered it offensive when it was used to describe people. It wasn't necessarily supposed to be offensive when used to describe objects. But as usual when it comes to censorship, the common sense and nuance of the situation is abandoned in favor of a blanket ban, just to "be safe." But for all I know, the people who first started questioning the word now consider it offensive no matter in what context it's used. The word has gone through an evolution in which it's now considered taboo and people in the media are "scared" enough to want to avoid the word completely.
No, Buzzr doesn't execute their policies perfectly and sometimes an episode slips through with the word "oriental" or with other words they wouldn't normally allow on the air. But those are mistakes and not their policy.
