> If a site-blocking order is an available remedy, what analytical framework governs its use, and how must this framework account for the impact of such an order on freedom of expression?

On the one hand, it's unreasonable to expect a court to specify a perfect algorithm for determining which sites can and can't be blocked, but on the other hand, the fact that such a dangerous remedy has been invented by the judicial branch, with no clear guidance from the legislature, suggests that the system needs to "fail open" by protecting fundamental rights, until the government can pass a law that gives some parameters to how this censorship power may be used.
