BB are pissed off because Vinnie had the balls to threaten THEM with legal action if they didn't abide by the rules THEY have put in place. Vinnie pulled them up about it and they don't like it up em.

The days of being able to manipulate the phone voting are over so if Vinnie wins its because he got the majority of the votes and there's little BB can do about it. Vinnie fans know that "what you see is what you get" - Vinnie hasn't tried to be anything other than himself and if the public don't vote him the winner I'm sure he won't give a toss because he's accomplished what he went in for which is generating massive publicity for himself and enhancing his no nonsense, hard man image which can only result in even more film roles for him. Hollywood love a "bad boy", so it's WIN-WIN for Vinnie whatever the outcome.

I think BB has had it in for Vinnie ever since he threatened them.... and its working, he is horrible towards some of the others.
Remember Marcus... BB edited him as negative as they could following Sree's eviction, about a week later they realised they made him more popular :D
