I also want to add one more thing. The people that claim the channel favors one contestant over another.. it's true. Of course they do, but it isn't about personal relationships, it's about money. At the end of the day personal relationships don't pay the bills or the employees a channel has so that won't last for long.
Contestants like Sidharth and Rashami are favored because they bring in viewers and votes which equal to money. People knew of them prior to BB. So yes, they do take some liberties with contestants like that and they have from season one. I'm not saying other contestants don't bring in money. Someone like Asim does but he made a chunk of his name in BB so now he's made a place for himself and will definitely make it to the top.
