I decided that I didn't like having to manually adjudicate results and didn't see a way around that.
I just checked and the site is gone.
No need to manually adjudicate results given a large enough market. Nash Equilibrium will force people to 'settle' their positions honestly if the only way with withdraw your funds from the betting pool is to agree to the split ratio on a market. Those who are willing to settle closest to 50/50 will be most likely to get their funds out of escrow in an ambiguous outcome. The honest players in the market will tilt the price for getting out of escrow in one direction or another and after the price crosses a 75:25 split, the network could automatically call it.
This entire algorithm could be implemented on a blockchain and be very reliable.
