I think the producers are running the show.
You used to have to text to vote, didn't you? Which cost you something. Now it's all free - which it wouldn't be if it was a nice little earner from texts.
The stiltedness is rally showing now. There are no (screened) conversations about anything interesting - there hasn't been a single joke about missing the footie, and I really wouldn't know the interests of any of them - on a first date, wouldn't you spend a bit of time finding out someone's interests? Ditto when you find yourself in a group who you're going to be with for a while. It's such a major gap
Also pissed off that none of the girls (yes, I know they're young women, but I'm old enough to be their mother, and at least this show is pretty even handed in calling the young men 'boys') ever does any exercise.
I'm sure the fashion chain that provides the clothes will have some swimming costumes/bikinis that you can actually swim in, and may well do sports clothes, so I can't see a sponsor-based reason why not to use the pool and outdoors gym, no reason why they couldn't have access to some pre-loaded work out vids. They could (if chaperoned) also go out for a run - hard to film, but you could get them coming back in. Getting a couple of runners in there banging on about splits would probably be even duller than much of this series, but at least it would show more rounded people that the viewer has got to know.
All I know about this bunch is they seem to have really endless capability to put up with seriously dull single-subject exchanges of monologues
