Of course, there are wiki's listing 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. <https://s3.amazonaws.com/s3.documentcloud.org/documents/1261620/torpedo-affidavit.pdf> -- Rejo Zenger E rejo@xxxxxxxxx | P +31(0)639642738 | W https://rejo.zenger.nl T @rejozenger | J rejo@xxxxxxxxx OpenPGP 1FBF 7B37 6537 68B1 2532 A4CB 0994 0946 21DB EFD4 XMPP OTR 271A 9186 AFBC 8124 18CF 4BE2 E000 E708 F811 5ACF
