Hass:
If you want a crowd to be controlled it aint too hard, the person who the crowd most respect (Davina) needs to lay down the law not necessarily directly but by hintful comments that will encourage more cheers and make Makosi feel better e.g. "I dont care how much this crowd boos, I have thoroughly enjoyed you as a housemate, and im sure that you will be remembered in big brother history for your great entertainment for a long time!" that'll hush the booers a little!
Alternatively, which could be an easier option, during the commercial break someone could loudpeak into the crowd saying "Any nasty, threatening or un-called for comments or booing during housemates interviews with Davina will result in persons being removed from the BB crowd, from the security guards."
That is how to control a crowd
