I guess they should just change the whole format and rules of the game. If a contestant walks out they come back in freely after a day or 2 and join the game as a contestant again, goes against the whole format of the show. A contestant gets kicked out but then is let back in, again goes against the whole format of the show.
Why not just allow all contestants a day out to see their family, and then return back, heck better yet, just giv em each an IPAD so they can check what everyone is saying about them. Let them go out and return back to the house at night time. Its stupid.
Other international versions of BIgg Boss are better as they conceal the outside world from the contestants, stick to evictions and no chit chat or gossip etc... But then again year after year Bigg Boss is becoming more of a holiday home, do what u want when u want.
Next season contestants will fight get kicked out or walk out and then realise they want back in and welcome back to the show. So silly! Whats the point, why even vote when either the person will get put in a secret bed sit or just go home and return again
