Well....
Given the current tactic seems be "Block the IP resulting from a DNS query", I can see them shortly resort to "just redirect the whole damn domain", followed by "just block access to DNS".
Because they are that stupid.
Incidentally, the court order to block a site (ala BitTorrent) - doesn't that just apply "to the ISP", rather than it's customers? As (IANAL) customers are not subject to the order - although they are impacted by the ISPs compliance with it, gaining access via other methods (another DNS/IP, or VPN) is not the fault of the ISP, or a breach of an order against it's customers, because one doesn't exist.....?
