The Consumer Financial Protection Bureau said they can't do much against individuals (they could have if DZ ran this as a corporation of sorts) however they suggested taking it to court.

I have recently become quite impatient at DZ's inactivity and am ready to get his ass served. So...

Here's DZ's real-life ID: Jason Badua
I confirmed it with thomas_s.
I found all his address/phone/email info here in this lawsuit (mainly under the 'billing address' info) he took up recently against a bitcoin miner manufacturer:

I've been emailing the addresses he has listed in this without reply of course for a couple weeks now. Haven't tried the phone number listed though.

Out of curiosity, who all of us had stakes in this non-refunded nodes? I only had 100 in node 3. I know Otoh probably had the largest.
