They were probably worried Mia would turn the DM convo into talking about how horny she was in the house and what she got up to last night. Yes this sounds gross and weird but I watch the live streams.
The one blessing of having a short season is that if BB can hold onto its #1 audience share through the entire run, next year it can come back with a higher budget, more sponsors and the production can shake off the Ch7 hangover and bring back the OG template.
