It just has to slow them down enough that a system (automated or not) could detect the escape attempt and initiate explodey explodeyness.
So even comparatively cheap strong materials may be good enough for a prison so long as it slows them down sufficiently.
Oh, all this thinking about stuff that hurts vamps... Why is vamp venom the only stuff that leaves scars? Shouldn't it, at most, do nothing of note to them? (especially if pretty much all their bodily fluids are replaced with it?)

I'm kind of bewildered about that too, to be honest; it just came out of canon. Handwave: it's foreign venom. It's like a small local immune response. (This meshes with a bit from Bree Tanner about someone licking her severed arm to let it knit back to its original location smoothly. No scarring is suggested to happen to this girl from her own venom.)
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
