Firstly, you need to make abundantly obvious and clear promises as to what happens to money left it accounts. There is no reason to trust your escrow, let alone your ability to manage or secure it. I honestly still can't find it spelled out clearly, and even then it'd be hard to trust.

I suggest you pull your site before this PR gets even further out of hand, then reboot. If you continue to pursue your project, partner with a couple projects that opt-in (free publicity for you both) and work to their needs. Once you have things in order, then you can think about something more automated.
