The avidavit answers my question:

  In order to identify potentiai "hidden services" invoived in the 
  distribution of child pornography, the NHTCU activaled a web erawier 
  to search avaiiabie "hidden services" within the Tor-netwerk. A web 
  erawier is a software program that can be used to automatically search 
  for websites, identify any hyperlinks cantairred on those websites, 
  and follow those hyperlinks to additionai websites. The NHTCU 
  configured the web erawier to search for "hidden services" ending in 
  ".anion" within the Tor network. Severai hundred "hidden services" we 
  re identified and documented bythe NHTCU. Each of these "hidden 
  services" was then manually reviewed by the NHTCU to determine whether 
  it cantairred child pornography. 
  
The typos are from the OCR.
