They were never going to give you recourse anyhow. They'd be idiots to do so. I certainly would not be willing to personally guarantee that hostile, intelligent human beings will not find some way past the security I implement. I'd love to be able to, but when the opposition is as smart as you and generally endowed with more time and motivation, giving out lots of recourse if they do manage to score some points is a fast route to bankruptcy.

If you think about it, most of our normal concepts of "recourse" involve things entirely under the other party's control, and in serious contracts, still often have a call out of "acts of God". It'd be like a football team offering legal recourse if the other team wins; not the brightest move.
