I like how my message to try abandoning captcha entirely came up with a myriad of complaints how we can be smart, enable new captcha which is unique, etc.
Let's measure the impact.
Could someone kindly please do some metrics on these cases after a user opened an edit box: - edit saved without a captcha - edit attempted to save, faced with captcha, didn't bother entering it and gave up - edit attempted to save, faced with captcha, attempted to save again without entering it, gave up - edit attempted to save, faced with captcha, attempted it once, succeeded - edit attempted to save, faced with captcha, attempted it once, failed, gave up - edit attempted to save, faced with captcha, attempted it twice, got it right on second try, saved the edit - ... (x3, x4, x5)
As I heard there were some "A/B" tests and such, and I imagine they could be capable of getting this information.
