Talk:CAPTCHA/Image puzzle CAPTCHA

This is an anti-captcha: annoying for humans (for the example shown on the mocks, solving the puzzle will be a very frustrating experience for someone who does not recognize the logo) but trivial for bots (just need to check which edges match). --Tgr (WMF) (talk) 01:29, 20 March 2014 (UTC)
 * There seem to be others who use puzzle captchas, so spambots could already be trained to solve them, in which case this proposal wouldn't work even in small wikis (unlike QuestyCaptcha). --Nemo 08:32, 20 March 2014 (UTC)
