Sometimes TPing yards was part of tradition. We used to b able to use common sense in enforcing rules, today all we have are bright line distinctions, if exceptions are allowed they are abused. So I do not think Carnival had a choice, they had to take some action because the problems were actually escalating. However, the kids causing the problems were already blatantly breaking Carnival rules, and nothing was done about it. Unless there is enforcement, it's just another rule to be ignored by many people.
