Re: Oh...?
From the linked-to Treasury page...
"...these digital currency addresses should assist those in the compliance and digital currency communities in identifying transactions and funds that must be blocked and investigating any connections to these addresses.
"As a result of today’s action, persons that engage in transactions with Khorashadizadeh and Ghorbaniyan could be subject to secondary sanctions. Regardless of whether a transaction is denominated in a digital currency or traditional fiat currency, OFAC compliance obligations are the same."
Read into that what you will.
