The GP comment was appealing to their own authority in a condescending way, I feel the tone was matched, but thanks for the feedback.

What you’re saying is true, although you can do simple blocks on user agent + geo ip alone and accomplish blocking a majority of bots anyway without captcha - but I’ll digress - that is not the topic of discussion. I’m not at all arguing that CAPTCHA doesn’t stop bot traffic - in fact my first comment says the opposite. Most bot traffic is extremely “dumb.” A mistake people make, which the gp comment seemed to, is that it stops bots dead.
