First, I agree that it probably won't happen.
Second, I'm not saying that moving the students to a new area will make the problem worse simply because of the area's location. I'm saying it will be worse because the message is sent that swearing wasn't permissible where the students were locacted, but it is permissible in a different area. How, exactly, does that solve the swearing problem? It doesn't solve a thing.
Third, the video idea is DOA. Everyone in the building is now warned that swearing is grounds for removal before each and every game. Everyone buys a ticket on which the warning is printed. To believe that a video will solve the problem is simply naive.
