I feel something is wrong with CAPTCHA on Electronics SE and Electronics Meta. For the last several days I ask something like no more than one question per day and I'm shown CAPTCHA almost every time.
Recently I asked this question and was shown CAPTCHA although I haven't asked or edited anything before that. Then I went here and posted this answer and again was shown CAPTCHA - I haven't done anything else on this Meta today.
When I tried to post this (the current) question I also was asked to enter CAPTCHA although no more than ten minutes passed between I posted the answer and I didn't do anything else in between.
So I feel CAPTCHA is too aggressive. What am I doing wrong?
