[1]http://bitcoin-brokers.org/, if its still operating, can be an
   important element in a thorough trade-craft of financial privacy. They
   act as brokers to enable non-AML/KYC purchase of bitcoin. Sellers
   escrow their bitcoin with the broker. Buyers deposit cash into seller's
   bank account at a branch teller, acquire and present proof of payment,
   via broker, to the seller. Assuming no dispute, broker releases
   bitcoins to buyer minus a reasonable commission. Because broker never
   touches any fiat they aren't technically an exchanger. Seller pays no
   commission (last time I checked) but is not anon to buyer (and of
   course broker).

     In bitcoin-related investigations, authorities will often follow the
     digital trail of an illegal transaction or suspicious user back to a
     specific account at a bitcoin trading company. From here,
     investigators will likely subpoena the company for records about
     that
     particular user, so they can then properly identify the person
     suspected of a crime. The Internal Revenue Service, however, has
     taken
     a different approach. Instead of asking for data relating to
     specific
     individuals suspected of a crime, it has demanded bitcoin trading
     site
     Coinbase to provide the identities of all of the firm's U.S.
     customers
     who made transactions over a three year period, because there is a
     chance they are avoiding paying taxes on their bitcoin reserves.
     Coinbase has a total of millions of customers. According to court
     filings, which were first flagged by financial blogger Zerohedge on
     Twitter, the IRS has launched an investigation to determine the
     correct amount of tax that those who use virtual currencies such as
     bitcoin are obligated to pay. But according to the documents, the
     IRS
     is asking for the identities of any U.S. Coinbase customer who
     transferred crypto-currency with the service between 2013 and 2015.
     "The John Does whose identities are sought by the summons are United
     States persons who, at any time during the period January 1, 2013,
     through December 31, 2015, conducted transactions in a convertible
     virtual currency," reads a memorandum written by Department of
     Justice
     attorneys and filed on Thursday, November 17.
