why don't bb just scrap the prize fund and then we'll see who is really "playing a game," and who is there for a laugh

no you won't. My guess would be most of the money housemates can make from BB is from media attention. Interviews, exclusives, dishing the dirty, etc....

It's contractual, I suppose. But yes BB could pretend that. Would be interesting to see how disappointed each HM gets.

They'd need a plausible reason. Too much rulebreaking, i.e. house total of strikes above a certain number? nd
