Hello - first of all, this is horrible news, and I hope it is resolved very soon. We're behind you 100%.

I am still unclear on 2 issues you mentioned.
1) Does Dwolla owe you guys any money? Have you lost any funds after reversals?
2) You said your blog post was going to walk us through how this happened, but I only see that it did happen, not how they/you were scammed. First the funds in the transaction you got were confirmed and then they were reversed. Do you know how the scammer got his transfer confirmed in the first place?

Best wishes.
