So I've been watching BB for several years now and there is something that I am very confused about. I'm American, if my name didn't give it away.

Why can they show taped swearing on the main show, but if someone does it live, they have to apologize? Were there really people that listened to Ashleigh's VT where she dropped 50 F-bombs in 20 seconds and were fine with that, but then were offended when she said the same word twice a few seconds later on live TV?

I know there are different rules for when you can and can't swear, so like when they had BBLB in the afternoons (mornings?) you couldn't swear at all, but on BBBM/BotS they can swear all they want and it is live. So what gives? Is there a special time in the middle where you can have swearing, but only if it is pre-recorded? This has never made a lick of sense to me.
