What we need is a list of netblocks used by the ISPs doing this.
Give the users from those netblocks an alternate page that explains they cannot access the content and should switch ISPs/complain at their ISP.

If we do it enough (we're not makign money from their customers anyway) the customer will get annoying enough to get the ISP to stop, or go out of business (either is good if they're this greedy).
