Cast going for other spouses

American here… I’ve watch every season of the US and am on Season 6 of the AUS (watched 1-5 so far) and I just don’t understand why the experts allow cast members are allowed to cheat or pursue someone else, especially when they are in another couple. I realize it’s for ratings but it’s ridiculous how they don’t stop it and the producers actually encourage it. It really takes away from the show and makes it just feel like you’re watching temptation island. Maybe the difference is that in the US they are really married and here they are just pretending.
