Par for the course when a housemate gets himself ejected, surely. That's why the rules are so important, it ties to the money and is included in the contract. However, with Biggins being removed so unceremoniously and without much (from our vantage point) support, I thought BB would pay him anyway.
Really, if the producers are going to pull something like this, they should show the audience all the "offensive or unacceptable language" (that's what the damn disclaimer is for) as well as all the warnings. Not only because this show is meant not to be constructed reality but also to help cover the showrunners own asses when they kick a housemate out over f*ck all.
