Someone claiming to be from Dwolla just called me to "verify details of my account" from a 515-422-xxxx number.  They wanted me to give my name and address.  I declined and said I don't know who you really are.  I've never done a single deposit to them, only withdrawls from Mt Gox and TradeHill.  

They may be quiet on this issue, but they're doing something to cover their ass now.
