In researching Exploding The Phone I spammed various federal agencies with hundreds of Freedom of Information Act (FOIA) requests. The FBI bore the brunt of my requests since I figured they were the agency that had the most info on phone phreaks. According to my tracking spreadsheet I sent them about 400 requests over the course of four or five years.
Recently Jason Smathers of Muckrock filed his own FOIA request to the FBI, asking them for a copy of their "vexsome filer list" (vexsome: adj., tending to cause annoyance, frustration, or worry ).
They sent him a copy. I'm on it:
You can see the details on his request and the FBI's response over on Muckrock's web site.
I note that there is something vexsomly and recursively delightful about filing a vexsome request for a list of vexsome requesters. :-)
 Although I'm thinking it should probably technically be "vexatious", not "vexsome."
