Comment (by phw):

 I just deployed a new batch of CAPTCHAs that I created after applying the
 following patch set to isis's [https://github.com/isislovecruft/gimp-
 captcha/ gimp-captcha]:
 https://github.com/isislovecruft/gimp-
 captcha/compare/master...NullHypothesis:fix/24607?expand=1

 Our BridgeDB metrics should soon reveal if 1) users will now be more
 successful at solving CAPTCHAs and if 2) the GFW will now fail more –
 either because their classifier (if they have one) does poorly on these
 new CAPTCHAs, or because they previously solved all 10,000 CAPTCHAs and
 are now unable to solve the new ones.
