This is a bit of a wild guess but would the reason be why the higher ups came down on the social team be because if all episodes were uploaded in one night, it would spam YouTube subscribers on their subscription feed? Cause while I don't personally mind Big Brother "spamming" the episodes as I do take an interest in them, I do know that when other channels do it especially channels I haven't engaged with in a while, I tend to unsub from it if there are more than 5 uploads a day from said channel. Anyway, just a theory!
