I'm pondering how much of my life I have wasted identifying street signs on ReCAPTCHAs because of #CloudFlare.

It's a lot. And I could have been doing many other things in that amount of time. I've started to close tabs if a site presents me with one; it's probably not important enough to waste my time.

Stop.

Normal users are getting screwed by this. Besides, it's crackable:

If your site is behind CloudFlare, disable this "protection".
