How often do captchas appear?
Why does SO think I'm a bot?
Please tone the captchas back down

I have very frequently been presented with the captcha page over the past few months. Since I have a reasonably robust history of participation on StackExchange sites, I'd think it were self-evident that I'm not a bot.

Why do I keep getting hit with the captcha?

EDIT: In the process of asking this very question no less! Post and then, bam, captcha!

  • I think my thinking was that I'd have to pass the Turing Test to be able to post an answer. Or something. I'm just going to change it. – jprete Nov 6 '11 at 3:34

    Jon Skeet submitted an SQL injection, changing the code and presenting all other users with CAPTCHAs, thus slowing us down and protecting his rep lead. Obviously. – Ben Voigt Nov 6 '11 at 3:41

I've noticed the test comes up when you make a lot of edits very quickly -- I imagine there is some heuristic which triggers the test.

  • I just got hit with a Turing Test while posting an answer. Lots of pre-post editing though. – Alex Hajnal Jan 6 at 11:16
