How often do you get CAPTCHAs, and what were you doing when it appeared?

Some future scripts I'm working on may attempt actions that could at times require a CAPTCHA, which would throw a big wrench into the gears. I'm just trying to figure out when I can expect to see them, and when I can expect to avoid them.

I myself have only had to answer a CAPTCHA once, and it was on my first post ever.

To trigger CAPTCHA while editing, asking, or answering:

  • The minimum window is 5 seconds
  • The maximum window is 40 minutes

There is a maximum of:

  • one edit every 30 seconds
  • one answer every 60 seconds
  • one question every 60 seconds

To trigger CAPTCHA while doing performing other actions, there are throttles of various sizes depending on the action -- it's mostly a "slow down" speed bump to inhibit potentially dangerous "I'm going to post obscene things as fast as possible!" situations.

edit: some new reductions in CAPTCHA throttle thresholds, if you have > 10k rep:

  • for edits -- reduced by two-thirds
  • for post submission times -- min seconds reduced by one half, max minutes increased by x2

edit: assuming you are a logged in user and have >= 200 reputation: after successfully completing one captcha, we now suppress captcha for 5 minutes on your account.

edit: the maximum window for submitting a post or edit has been removed.

Thanks for the exact answer –  Ian Elliott Jul 3 '09 at 23:50
Interesting... so I could post around 1400 questions a day? –  DisgruntledGoat Nov 17 '09 at 19:58
@DisgruntledGoat :D Actually, as far as I know, there is a 50 question per 30 day limit. You could try though... –  CoffeeRain Mar 26 '12 at 19:44
I assume the 10k check is only on that one site, not network wide? I seem to hit the Captcha a lot on new sites. –  Ben Brocka May 18 '12 at 23:38
