When I get a captcha with the letter O, zero, numeral 1, or lowercase L in it...

... I keep hitting the refresh button until I get one without any of those characters in it. There's no way I'm ever gonna guess what character they intended. lol

LMFAOLMFAO right?!?!?

Captcha is a heinous atrocity, but what can ya do!

what can ya do!

The best captchas are the ones that don't use images.

Captcha: "What color was George Washington's white horse?"

Human: "white"

Most developers are aspies who cannot think outside the box.

Yeah exactly, those are the best... like anybody who can't answer that question doesn't need to be on the internet let's be real.

It's such a low tech solution that literally gives you the answer - yet it stumps the captcha cracking bots, which is the whole point of captcha.

I can see why the ReCAPTCHA people are invested in over-engineered solutions though. That's their bread and butter product.
