Just playing devil's advocate here.Gina, Hunter and the early bootees may have said nice thing about Rob simply because he was rather nice - to them at least during the game. All of his scheming took place in confessionals, and all of his ugly statements were made to Sean. Currently, he's bickering with John - these 2 haven't been voted off to give us any opinion. Don't forget, they used to do the morning show and have a really great time over at Mumu. And Rob himself was never actually called "lazy" by the others - that description was used for Sean and Sarah.
I'm not saying that the Rob spoilers are no good, but they aren't air tight. If I were out there, I'd be voting Rob, but I'm not out there and some of the things these guys have done have not made a whole lot of sense. Somehow, I just don't think MB would let us have 2 gimmes in a row.
Just food for thought.
