Declaring the game a forfeit

[CJP]

I was a spectator at a game the other day where a very good team was playing a very weak team. The good team applied full court pressure the first quarter and jumped out to a 20 point lead by the end of the first 8 minutes. A couple of minutes into the second quarter, after a timeout, the weaker team began intentionally rolling the ball to the opposing team. This went on for 4-5 intentional turnovers which turned into unopposed layups. It was very embarrassing for those kids. Their coach was on his feet encouraging them to "do it again" each time. After the 5th or so intentional turnover, the better team backed off of the full court press and the other team began playing again. I thought to myself, if I was officiating this game, at what point do we stop the game and call it a forfeit? What if the better team kept up the pressure? Has anyone ever had to declare a forfeit due to a situation like this? What would you have done if it continued?
