Ahh, makes sense. I actually found many different and interesting solutions to pascals mugging with my search terms though. Just not this "counter" solution.
This thread already shows up pretty close to the top for searches of "pascals mugging solutions" that I've attempted. For that exact phrase it's number 3, and has been before you posted this. I don't know that this particular solution needs to be more closely associated with the search terms then it already is.
Eliezer presented a counter solution similar to this on Overcoming Bias. search fu
Now I tend not to follow this form very much, so please excuse me if this has been suggested before. Still, I don't know that there's anyone else on this board who could actually carry out these threats.
If anyone accepts a pascals mugging style trade off with full knowledge of the problem, then I will slowly torture to death 3^^^^3 sentient minds. Or a suitably higher number if they include a higher (plausible, from my external viewpoint) number. Rest assured I can at least match their raw computing power from where I am. Good luck.
EDIT: I'm told that Eleizer proposed a similar solution over here, although more eloquently then I have.
