I don't get it either. I said it the other day, it's very confusing now what is allowed and what isn't.

It used to be any kind of conversation years ago, it was obvious what was rule breaking straight away. Now it really feels like BB just pick and choose whenever they are in the mood to punish, or when it suits them to protect their favourites.
Fair enough they can change the rules at anytime, but it's a complete joke now as they don't change them when it really matters, like last weeks nominations being the perfect example.
