I'm wondering when at what threshold it stops. I know I don't have a lot or reps but I don't remember seeing a captcha after my first day. The other day I had to fill a captcha to post a new question. Filling it out is not a problem, but I'm just wondering if there is a threshold or do the guys with 200k reps see them once in a while.
The rate at which are you asked to fill out a CAPTCHA is reduced as your reputation increases, but you are still asked.
