Uh oh,
After a quick review of the posts that claim successful doubles, it appears there is some lying here:

BitMofo claims to have sent 1 BTC to "max in montreal" with transaction ID 4ed0269f3ed3d0131b474c7b33fde43bdf869b46c102494a7e7176cf52874c57
This transaction indicates that BitMofo owns address 1CyKTdcEHjWtD9FuamThfQA2cjbHvYQnzy

Then later BitMofo claims "Another doubled" sending 4 BTC to 1CyKTdcEHjWtD9FuamThfQA2cjbHvYQnzy

So the 4 BTC was just sent by BitMofo to himself.

I suspect that the lie was necessary to get the ball rolling, but it makes me wonder just how many more of the supposed doubles were "priming the pump" or sock-puppets.  Still hoping for mine to get doubled, but starting to think I'll have to write off my contribution.
