I filed a FOIA request about Cryptome with DHS a while back:

     Any records relating to Cryptome, also known by its web address of
     Cryptome.org, which posts pictures of sensitive sites and potential
     security holes as described at
     [1]www.nytimes.com/2004/08/29/nyregion/mapping-natural-gas-lines-adv
     ise-the-public-tip-off-the-terrorists.html by the New York Times.

   s-22647/
   Sent through MuckRock on December 1, acknowledged on December 2. Also
   closed on December 2, according to the DHS FOIA website. No
   notification or explanation provided, not through MuckRock or to me
   directly. I say to me directly because they also closed another FOIA of
   mine without explanation, insisting on opening a new one when I tried
   to follow up within the 30 days.

   Weird, right?
