This Page Is Anonymous (2013)

SDF lets you register an anonymous user over ssh (which is accessible via the Tor network) and takes cash over mail in order to validate the user. This page was registered in exactly this way: I created a user called “voidnull” over ssh over Tor, then mailed SDF a single dollar bill with no return address. As far as I interpret the rules, there is nothing illicit about using Tor to access SDF, or setting up an anonymous account, so long as no other illicit activity takes place.
