Why isn't anyone asking where Google's recaptcha images are coming from?
Yesterday, the challenge i got was clearly obvious, it was a car shaded by a tree shown from side view and it looks like someone unknowingly holding his/her device pointing to it (bloatware i suspect). And today i am told to pick "stairs". Yes! from someones fucking home! No sugar-coated explanation is justifiable enough for this sort of fuckery!

@frogstair Street view I guess

Y'all trained Googles ML-Networks since recaptcha exists.
It started with Googles mission to scan books, so they needed help with hard words.
Than they did Streetview and wanted to optimize the Streetnumbers, so they added that. Now it's Streetview training on steroids, meaning widespread object classification. Signs, objects, etc., with much of the trained data going into GCP products and for internal use.
It's a closed loop and it's not necessarily bad. Everyone gains from it, Google, who can make money of it and continue to develop for its own products, external business, that can build products with the help of said data for almost stupidly cheap and in-cooperate it into own products, and we (as user) to have access to always evolving and more advanced products, helpers, phones etc. etc.
So Win-Win-Win?
Almost forgot the webmasters themselves who get good, free, easy to use and well known captcha for their sites

@Kimmax you forgot car driving ML...

I really thought the fact that Google bought recaptcha to provide a massive supervised learning dataset for its streetview images was common knowledge...

hCaptcha is pretty cool. Behaves almost like Google reCaptcha

@PublicByte Sorry to be the first one to tell you that, but you're a bot. Humans get them right on 3rd attempt at most.

@PublicByte Spam prevention by rewarding users? This does not work for registration forms.

@PublicByte See? I told you.

It’s your birthday. Someone gives you a calfskin wallet. How do you react?

You’ve got a little boy. He shows you his butterfly collection plus the killing jar. What do you do?

You’re watching television. Suddenly you realize there’s a wasp crawling on your arm.

You’re in a desert walking along in the sand when all of the sudden you look down, and you see a tortoise, crawling toward you. You reach down, you flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over, but it can’t, not without your help. But you’re not helping. Why is that?

Describe in single words, only the good things that come into your mind. About your mother.

@FrodoSwaggins not really going to work. First they run the same images to multiple people and even when people get it wrong they learn which parts is ambiguous.

But sometimes they already know the answer and if you answer all wrong they just filter out those.

And remember, most users still want to access the service so in total, quite few will do this so google will not be very affected.

@FrodoSwaggins possibly, but I doubt you can convince enough tondo a difference :/
