#CloudFlare is now hitting the archive.org wayback machine with the same #CAPTCHA as #Tor users, thus censoring history too.
@gerowen indeed, #Google is using #CAPTCHA to exploit labor, which in some situations in the US amounts to a 13th amendment issue (involuntary servitude). Google's CAPTCHA also gives preferential treatment to logged in Google users, which adds to the tracking of those users by associating them to the site where the captcha is presented.
