You're exactly right. There has been a lot of study of this by courts in the United Kingdom. The argument that has been put to those judges is that these orders are easy to circumvent, and they will be. The judges have actually found and expressed the opinion that in fact most users are going to abide by the order. They're not going to circumvent; they don't have the technical skills. Only a small number would, but that small number doesn't undermine the fact that these orders are effective.
