Write a web client to periodically fetch this static webpage via Tor and record how often a CAPTCHA is returned +3. Record and graph CAPTCHA vs real page rates 4. Using the pre-existing architecture, run a second client that does not fetch this webpage via Tor. This will allow us to contrast and compare how Cloudflare responds to Tor Browser vs other browsers. 5. Track and publish these details publicly There are two interesting metrics to track over time: -- the fraction of exit relays that are getting hit with captchas, and -- the chance that a Tor client, choosing an exit relay in the normal weighted faction, will get hit by a captcha. +- the fraction of exit relays that are getting hit with CAPTCHAs, and +- the chance that a Tor client, choosing an exit relay in the normal weighted faction, will get hit by a CAPTCHA. Then there are other interesting patterns to look for: - Are certain IP addresses punished consistently and others never punished? -- Is whether you get a captcha much more probabilistic and transient? +- Is whether you get a CAPTCHA much more probabilistic and transient? - Does that pattern change over time? # Resources
