Wow, if you brought a paper contract to court that mutated itself depending which way you look at the paper, I wonder what a judge would think of that?
Personally I would crumple it up and pitch it out the window. I don't know why they can't simply be clear about what clauses apply to which geographies. An IP address should not be assumed as a reliable indicator of the jurisdiction in which an end-user resides. (Eg. In addition of VPNs's and unexpected routing, what happens if you travel?)
