Captcha forces people to mark mailbox as parking meter (twitter.com)

If the image classifier it's training has learned that mailboxes and parking meters are the same thing, I wonder if there's any way to fix that without starting over!

Now I'm wondering about adversarial responses to captchas that would make unrelated objects indistinguishable to the AI...

The AI is gaslighting you. ReCaptcha lets you through with wrong answers. Try it.

The only pattern it seems to block is repeatedly smashing the skip / ok button.

Mislabeled images. This is going to be common and who knows how they are planning to use that data.

Many websites don't need captcha anyway. They could go with options like OOPSpam API and silently flag spam based on Spam Score.

Sometimes I play with giving some false positive to my capacha results, it's fun to see the AI accept or not my responses...

As for parking meters, in France, I never saw parking meters like this. We have different kind of ticket distributing machines.

There are five lights! You have 20 seconds to comply.

Lately googles captcha has become so difficult that half the time I'm unable to complete it.
