Regarding the 'quality' of the contestants, I've heard from a friend who works at ITV that since they bought in that friends/relations can't proxy use their social media during the show that they are having real trouble recruiting. They are also giving a stronger message to those who apply that more than likely - in fact at least 99% - they will have to return to their day jobs and not to burn any bridges before coming in.
