Maybe Ray was doing it on purpose when the camera wasn't on him? The camera did only focus on one of them at a time. I just can't imagine a film crew being that incompetent.
The director/producers most likely didnt give a fukk; i've worked on reality, lowkey it's pretty fun of how little fukks the higher ups give, but it could also just be ray j not thinking about it and no one wanting to deal with constantly telling him to stop doin that
they were there for hours im sure the hat was the last thing people thought about
Doing one camera at a time would take waaaay too long, it was prolly 2 cameras shooting across each other
