Guys, let's talk about ReCaptchas, where you click certain pictures to clear the captcha. Sometimes you don't have to click any picture, and I'm fine with that. But here comes the irritating part of these captchas, I finally see verify button after clicking like 50 cars and I say "Thank God", But NOO!! I get welcomed with a message "Please try again", and then click 50 street signs again. 
Okay my brother ..
ReCaptchas, is a very useful identification engine to avoid abuse of our account, the system works to test the foresight and ketelitan against an object .. if not human, impossible robot can access the account .. so you have not been careful of the image, because not a few images that are seen vague it means you have to jelly .. so roughly .. hopefully useful ..
