Ok, so this is another "I told you so" post, but allow me to bring this up, when I offered my bet that pbmining was a ponzi about to collapse, I didnt accept the betting terms about the website being online, and pb still paying out 'something' after x months. Instead I  insisted on this: " I also want to stipulate that I win the bet if payouts substantially diverge from theoretical mining yields. So for instance if pbmining comes up with some new fee or whatever, to reduce payouts to a few satoshi, or declares being hacked/fire/whatever and begins paying out just a fraction of what would be expected based on difficulty, I still win."

The bet wasnt made, but now you understand why I insisted on this and why I am not in the least bit surprised.
