Amusingly, CloudFlare would probably be in a position to do so because they present many Tor users with CAPTCHAs. While this has annoyed Tor users quite a bit, if we assume that * old and new Tor users are about equally likely to attempt the CAPTCHA * old and new Tor users are about equally likely to pass it * old and new users visit a similar proportion of CloudFlare-hosted sites via Tor exits * CAPTCHAs are relatively effective at preventing access by bots * CloudFlare keeps logs that clearly identify total volumes of successful CAPTCHA completion from Tor exit nodes then CloudFlare would have good, meaningful data about trends in human use of Tor. They wouldn't know the overall volume of human or bot use of Tor, but they could tell pretty accurately when human use is up or down and by what fraction. One confounding factor would arise if the new users are significantly more or less likely than old users to use onion services. I'd be happy to ask CloudFlare if they'd be willing to share this data (maybe in relative rather than absolute numeric terms, like "the number of people successfully completing a CAPTCHA per day from a Tor exit node on September 1, 2017 is x% of what it was on January 1, 2016"). -- Seth Schoen <sch...@eff.org> Senior Staff Technologist https://www.eff.org/ Electronic Frontier Foundation https://www.eff.org/join 815 Eddy Street, San Francisco, CA 94109 +1 415 436 9333 x107 -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
