I have also messaged game-protect to confirm/deny that he is holding money in escrow to guarantee payment of participants.

As an update, I have received no response from game-protect, even though he has posted since I sent my PM.

Also:

Payment method: BTC | GamblingTec is trusted since 2006

Domain name: gamblingtec.com
[...]
Creation Date: 2013-07-21T12:12:46.00Z

The underlying company has been around since 2006, it owns hundreds of brands... GamblingTec.com is one of them.

Do you have any update on your escrow agent confirming he is in fact holding signature campaign funds for you?
